The Wessex Hillforts & Habitats Project

Early morning last week…a drone took off over Hambledon after light snow. Perfect conditions, the snowflakes had settled into the valleys of the great encircling hillfort ditches… and streets of round house platforms became visible as rows of hollows outlined in white.

Hambledon Hill light snow shows the dimples where Iron Age round houses once stood.

These photos help illustrate the majesty and awe of this vast archaeological site and has helped us launch the National Trust’s Wessex Hillforts and Habitats project. With the help of Marie, our project officer, the People’s Postcode Lottery have granted over 100,000 pounds to get the project started.

The primary purpose of the project is to enhance the conservation of 13 NT Iron Age hillforts scattered across Dorset and South Wiltshire …but it will also inspire people to get involved and to carry out monitoring and research. It will also create new interpretation to bring these grassy hill top earthworks to life as places to be appreciated, valued and better understood. Alongside this.. to highlight nature, particularly the plant and insect life. Each hillfort’s unique topography nurtures precious habitat undisturbed by agriculture for over 2000 years.

So.. where are these places. I’ll list them out for you…. and as some have featured in previous blog posts I’ll reference these while we have a quick tour.

We’ll start in Wiltshire and from there head south and west and eventually end at the Devon border.

Figsbury Ring, north-east of Salisbury. A circular rampart and ditch with a view back to the great cathedral spire. Strangely, Figsbury has a wide deep ditch within the hillfort ..potentially Neolithic but there is no rampart.. where did all the chalk go?

Figsbury Ring from its rampart top showing the wide deep ditch inside the hillfort.

South of Salisbury, Wick Ball Camp above Philipps House, Dinton.. NT only owns the outer rampart.

Then there is the icon of Warminster, Cley Hill (blog posts “Upon Cley Hill’; Upon Cley Hill 2”), a flying saucer shaped chalk outlier with two round barrows on the summit..a strange hillfort.

To the south west, at the source of the mighty River Stour, is the Stourhead Estate with its two hillforts. These are Park Hill Camp, its views hidden by conifer plantation and Whitesheet Hill  (blog Whitesheet Hill Open at the Close) with wide prospects across the Blackmore Vale towards Hambledon and Hod. We’ll follow the Stour to reach them.

Hod is the largest true hillfort in Dorset, the geophysics has shown it full of round houses…a proto town… and there are the clear earthworks of the Roman 1st century fort in Hod’s north-west corner (blog post Hod Hill Camp Bastion)

Hambledon is close by, just across a dry valley, perched high on a ridge, surrounded by the Neolithic, you feel like you’re flying when standing there. (blog post Archaeology SW day 2014, Hambledon Sunset)

Follow the Stour further south and you reach the triple ramparts and ditches of Badbury Rings on the Kingston Lacy Estate. From here you can see the chalk cliffs of the Isle of Wight (blog post Badbury and the Devil’s footprint)

Now from Badbury take the Roman road west to Dorchester and keep going beyond the county town, glancing at Maiden Castle as you pass(Duchy of Cornwall, English Heritage).

The Roman road continues straight towards Bridport but branches from the A35 road before you reach the village of Winterbourne Abbas.

It has now become a minor road.. a couple of miles on… it branches again..still straight but this once arterial Roman route to Exeter has dwindled to a narrow trackway with grass sprouting from the tarmac.

Don’t lose heart…keep going…and you will break out onto the chalkland edge and the multiple ramparts of Eggardon Hill.

From Eggardon, the other hillforts emerge as sentinals ringing the high ground overlooking the Marshwood Vale, and, to the south, the cliffs of Golden Cap.. and beyond, the sweep of Lyme Bay and the English Channel.

Winter woods at Coney’s Castle

Next to the west is Lewesdon Hill, a small fort but occupying the highest land in Dorset, nearby is the second highest, the flat top of Pilsdon Pen, surrounded by double ramparts and enclosing Iron Age round houses, Bronze Age round barrows and the pillow mounds of  the medieval rabbit warren.

The last two in the Project guard a gap through the Upper Greensand ridge at the Devon border. Coney’s Castle has a minor road running through it and on its south side are wonderful twisted moss covered oaks… and beneath them the deep blue of bluebells in the Spring. Lambert’s Castle was used as a fair up to the mid 20th century, remains of the fair house and animal pens can be seen there ….but once again the views are spectacular, particularly in early morning after frost with the mist rising from the lowland.

Lambert’ s Castle after frost.

A baker’s dozen of hillforts of the 59 the NT looks after in the South West.

One might imagine that these huge works of humanity look after themselves… but they need to be cared for.. we must have farmers willing to graze the right number and type of stock on them….at the right times;  NT rangers and volunteers to cut regenerating scrub and fix fencing and gates…

If not, these nationally important scheduled monuments and SSSIs will deteriorate. The earthworks will become overgrown and grassland habitat will be lost, archaeological knowledge locked in the layers beneath the soil will become disrupted… and the views into the landscape and across and within the hillforts will become hidden.

The Wessex Hillforts and Habitats Project promises to be an exciting time of conservation and discovery. The work has now begun!

Shapwick’s Roman Fort, Kingston Lacy

This is the view along the Shapwick Road across our field towards Badbury Rings.

This is the view along the Shapwick Road across our field towards Badbury Rings.

Let’s walk across a Dorset field. It’s a good one.. and although we’ll stay in the same space we will be hopping about in time a bit. Well- we’re archaeologists after all.

For the moment it’s late summer, the corn’s been cut and as we leave the far hedge and walk diagonally towards the road our boots crunch on the stubble. Keep your eyes down, there are all sorts of things beneath our feet.

Yes. There. See it ? Sticking out of that tractor rut a black chunk of pottery. Pick it up.

On the upper edge it’s polished but on the rougher zone below you have that typical cross-hatch pattern. Iron Age? Roman?

I call this the ‘Long Field’. Not its old name.. but definitely very large and long. You’d notice that if you divided it up and surveyed it. There’s Geoff, laying out the grid, walking up and down with the magnetometer. He was the first man to map the archaeology here. I walked with him some days fixing the pegs, positioning the lines. We walked miles.. but the results were spectacular. Thanks Geoff.

The field is bottom left. This is Geoff's magnetometer survey showing the fort in detail and the underlying Iron Age settlement. If you look carefully you can see the parallel side ditches of the Badbury to Dorchester Roman road. Our walk is from fort entrance to fort entrance. From middle right to bottom left.

If you look carefully you can see the parallel side ditches of the Badbury to Dorchester Roman road. Our walk is from fort entrance to fort entrance. From middle right to bottom left.

You almost missed that. An orange samian base fragment. It has that silk sheen to it. Unlucky, the potter’s stamp is fractured at the edge and we can’t quite read who made it. Came all the way from Gaul though.

We’re approaching a large’L’-shaped trench. Ian’s in a ‘bee-hive pit, narrow at the neck and twice the width at the bottom. It’s cool down there. He hands up something like samian except it’s ruby-coloured. An earlier pottery.. dates this grain storage pit to the Late Iron Age- 2000 years ago.

At the other end of the trench is Martin..he’s in a large pit. No, he’s gone,
someone’s placing a dog in the pit on top of a piglet. The field’s disappeared.. there are circular houses all around us, a hub-bub of people livestock and wooden fences within a settlement stockade.

Gone again.. the place is blacksmith’s workshop, furnaces and hearths. These guys look Roman.. at least the pots are 3rd century style.

From scaffold tower to scaffold tower. Looking towards the  trench to locate the SW entrance of the fort.

From scaffold tower to scaffold tower. Looking towards the trench to locate the SW entrance of the fort.

We’re in the field heading to another larger longer trench with a scaffold tower beside it. This is the main highway, the Roman road from Badbury to Dorchester but we are also in the middle of a large Roman fort.

It was first seen on aerial photos in 1976, three concentric ditches with rounded corners. The first idea was that it was 1st century.. built on top of the Iron Age settlement right after the Roman Conquest of AD 43-44. Very different to the Roman fort at Hod Hill a few miles away though. It has only two entrances, one in the NE corner and one in the SW… and the ditches at the corners don’t quite match.

Let’s climb the scaffold tower and look down at the trench. We’ve put it at the SW entrance. We can see the three ends of the ditches in plan. The road metalling has sunk into the soft ditch filling so it has not been ploughed away.

The fort SW entrance from the scaffold tower. The outer ditch terminal is clear with remains of road metalling crushed into its surface. The middle and deep inner ditch have not yet been excavated. Most of the upper layers including the road have been ploughed away over hundreds of years. This land was part of the Shapwick common fields in the medieval period.

Most of the upper layers including the road have been ploughed away over hundreds of years. This land was part of the Shapwick common fields in the medieval period.

Gerald, Becki and Rob, if you could just remove the upper layers..yes, there are the ditches filled with pottery, animal bone and the occasional coin. It seems to date mostly to the end of the 2nd century. The outer two ditches are only a metre deep but the inner one is massive.. over 4m deep. Strange, some of the finds are 4th century.

Here it is..white chalk ramparts with a timber wall along the crest of the innermost defence. Inside it is full of rectangular buildings. Curious, the Dorchester road is blocked by the fort gates guarded by soldiers. They’re checking all the traffic. The Saxon raids along the coast have increased in recent months and this place, Vindocladia, is vulnerable. They haven’t the resources to build stone walls like those at Durnovaria (Dorchester). This secure place, the burgus fort, will have to do the job. A place of last resort for the Romanised Brits. Tense times.

Lets climb down from the scaffold and get into the car. I hope you enjoyed my favourite field. Nancy climbs in beside us. “How was it for you”…. “The earth moved”.. it certainly did.. and there was so much in it!

Archaeology SW Day 2014: Hambledon Sunset

This is the time to review the year and say thank you. The Christmas Archaeology Day is a good time to meet up, celebrate and share SW conservation work and discoveries.

We met at our new office at Tisbury.

Nancy organised lunch and talked about two Gloucestershire sites. Crickley Hill, which has had its archive and finds assessed this year (Crickley is a hillfort overlying a causewayed enclosure excavated 1969-93) and Chedworth Villa (analysis of the finds from the museum have highlighted some important new information about its Roman owners.. watch this space).

Nick (see FragmeNTs) talked of developments at Stonehenge and Avebury. Results from geophysical survey beside the great Avebury henge indicate an early settlement there and she also gave the latest on the plans for a dual carriageway tunnel under the line of the present A303 beside Stonehenge.

Jim brought a ‘Jamaica Inn’ style atmosphere to the room as he spoke of the wreck of the frigate’Royal Anne’ on Stag Rocks south of the Cornwall’s Lizard peninsula. In 1721, a naval ship, bound for Barbados was driven onto the rocks during a storm. The locals picked over the remains to remove valuables. The bodies of the crew are thought to lie in a narrow valley above the cliffs known as Pistol Meadow. Bournemouth University have geophysed the field and a scatter of trench and pit-like anomalies suggest the locations of mass graves.

Mid afternoon and we piled into cars and headed for Hambledon.

Last year we went to Whitesheet Hill on the Stourhead Estate, it rained hard and we got soaked but a good experience. The year before, a windswept bitter day. Cley Hill near Warminster circled by a war of showers, rumbles and shafts of sunlight. This year looked very promising.

We set out late. A squadron of 5 cars. The route rather convoluted between Tisbury & Childe Okeford. Out of the Nadder valley, over NT’s Win Green Hill, along the brink of the chalkland valley bordering the NT Fontmell and Melbury Estate and down into the Blackmore Vale. 3 cars made it to the lay-by. A phone call spoke of a traffic jam at Fontmell Magna so we climbed the hill.

Friday's sunset through the SW gateway into Hambledon Hill. The photo is taken from a large oval terrace cut into the slope of the hill. This was the site of a significant round house in the Iron Age.  This thatched timber framed building would have been the most prominent structure if you were to enter the hillfort over 2000 years ago. The entrance track splits in two in front of the building. The way forward either NW or SE of it. You would have entered the fortified settlement through double-leaved timber gates. Now the gateway is a grassy gap between banks as shown in the picture.

The sun was setting as we neared the summit. The sky cloudless and clear. The SW entrance was protected by a funneled corridor approach between banks. There was a gap between the ramparts which once held massive double-leaved gates. We passed through.. and in front of us was a raised platform cut into the slope. We stood on it and looked back towards the sun. This terrace must once have held a large timber round house and as we continued up hill, smaller hollows and platforms could be seen all around us. There had been 100s of buildings here over 2000 years ago.

At the top of Hambledon’s chalk ridge we found the remains of a Bronze Age burial mound.The low winter sunlight was showing up the faint earthworks beautifully and traces of narrow ridge and furrow here were evidence that the summit had been ploughed briefly during the Napoleonic wars. Now the long concentric circuits of massive ramparts and ditches could be better appreciated.

The view south from the southern rampart across the hillfort interior. Middle top left is the SE entrance. It is thought that it was here that a charge by Cromwell's cavalry was driven back by musket fire from the Dorset Clubmen who had occupied the hillfort in 1645. Top left is the central dome of the hill which is the site of the causewayed enclosure dated c.3600 BC.

Top left is the central dome of the hill which is the site of the causewayed enclosure dated c.3600 BC.

We walked north towards the middle. Here, a cross rampart blocked our way. We climbed it and looked back. The inturned SE entrance was clear and beyond it the dome of the hill top where the great causewayed enclosure had been excavated in the 1970s. Dated to c.3600 BC, the people of Hambledon hillfort lay mid-way in time between us and them…. but in 1645 Oliver Cromwell fought the clubman here. Back then, a mere 370 years ago. Volleys of musket fire from the Dorset ‘clubmen’ (who supported neither King nor Parliament) drove back a cavalry charge from Cromwell’s besieging forces.

The Wiltshire rangers arrived from Fontmell. Ben, who has recently led the repair of erosion scars at Figsbury Ring and Cley and Mike who’s formidable work on the Stonehenge Estate has led the conservation of the earthworks on the World Heritage Site.

We continued to the long barrow and wondered what this long ridge on the summit was. A 5,500 year old communal burial place or something else? It had been dug into in two places. Perhaps the work of Edward Cunnington who excavated here before 1894.

Two more silhouettes approached. Dave and Gill had found us at last. Dave had geophys mapped the whole of Hambledon and nearby Hod Hill. Gill monitors and records the Brownsea industrial archaeology as the sea gradually erodes the island’s shoreline.

One more stop at the northern cross-ditch. Some think the hillfort developed over time. First the northern third, then the middle section including the long mound.. and then the southern third was finally enclosed. The pottery from the northern ditch is Early Iron Age.. All Cannings about 500 BC.

A plan of Hambledon. The top northern part of the hill probably contains the earliest part of the hillfort. The remains of its southern limit can be seen as a cross-rampart just north of the narrow neck of the hillfort. Later, this neck was included within the defences and a second east-west rampart was constructed on its south side. This new area included the long barrow aligned north to south on the summit of the neck. It is thought that the southern part of the hillfort with its SW and SE entrances was the last part of the hillfort to be enclosed.

“Look!” said the astrophysicist, ‘the last before solstice’ and as small dots on the whale-back of Hambledon, we felt the ancient world turn. We watched… and the bright full moon erupted from Melbury Beacon as the vivid orange sun plunged below the Childe Okeford horizon at our backs.

Steep climb to the wow!

It’s easy to take for granted the archaeology in the landscapes we work in, those special sites we can visit when ever we need to replenish our souls. All the archaeologists in the National Trust are spread across all the different places and landscapes in the Trusts holdings, each with a range of sites and wow’s.

Hambledon Hill

Hambledon Hill

We try to all meet up a few times a year to discuss common issues and share new discoveries and ways of working. The last gathering was down in Dorset here in the south-west, and we managed to do a whole day in the field, working on site management issues. The ‘fields’ we choose were  the adjacent hill forts of Hambledon and Hod. Two of the 7 and a half  hill forts we look after in Dorset. The climb up and down and up and down again was helped by a stop mid way for tea and biscuits provided by the Rangers who manage the sites and had joined us for the day.

As we reached the top of Hod Hill we got our first glimpse of the size of the ramparts and scale of the area inside them. Hod Hill even has room for a Roman fort in one corner!

With colleagues from areas of the country that don’t have many hill forts or any at all,  commenting on how lucky we were in Dorset to have such magnificent monuments in our landscapes, I saw these sites with fresh eyes.

Chedworth and Sir Ian’s lost archive

Long ago, fresh out of school, I was told by Bill my mentor, that archaeology is an unrepeatable experiment.. you destroy what you uncover and you must record it properly. An excavation is never over until its published. This is the heavy weight of responsibility for all who go out and dig holes through ancient sites.

September 2000, a Roman wall footing from Badbury temple. Finally written up and sent for publication yesterday.

September 2000, a Roman wall footing from Badbury temple. Finally written up and sent for publication yesterday.

So.. part of my guilt trip is almost over as yesterday I sent the written report for Badbury Temple (dug in 2000!!!!) to Paul for publication. Nancy has sent out and gathered the specialist reports, Maggie has assembled her finds illustrations, I’ve got a drawing to finish this afternoon and then it’s done.

But…what if something happens?

Uncovering  and recording Sir Ian Richmond's excavations of 1958 and 1963 of the early North Range baths, Chedworth.

Uncovering and recording Sir Ian Richmond’s excavations of 1958 and 1963 of the early North Range baths, Chedworth.

We dug at Chedworth Roman Villa this summer and essentially were confirming something that was dug back in 1958 but never published. Chedworth’s a bit like that, lots of digs but little has been written up. From 1957-1965 Sir Ian Richmond investigated and re-interpreted Chedworth but he died in 1965 and his knowledge was lost to us.

Where were his excavation notes and drawings? They should be at Oxford University because he was a professor there but this trail seemed to have been followed in the past. I was told that the Bodleian Library only had a few notes.

In preparation for the dig this year, I reread the 1979 guide book.. because it has the best description of the North Range baths. In the introduction was a thank you to the archivist at Oxford for his help. I wrote to Roger, the author, and he told me to contact the Sackler Library.. so I did.

The nice lady on the end of the phone said that I should e-mail Graham. “I suppose you don’t have anything relating to Chedworth and Sir Ian….”

The Bodleian Library, Oxford.

The Bodleian Library, Oxford.

“Certainly, a stuffed box file with drawings and notebooks.. when would you like to visit?”

So on Monday I travelled into one of the world’s heartlands of learning..parked and took a double-decker into the ‘city of dreaming spires’. First to the vast Neo-classical Clarendon Building, where I handed in my form and was issued with a pass card. I had to read aloud a declaration saying that I would not light a fire or take a naked flame into the library… I agreed.

Then down Broad Street, past the Ashmolean and the Institute of Archaeology and round the corner to the Sackler. I pushed open the heavy double doors into the circular vestibule watched over by a porter (bit Harry Potter). Graham met me and swiped my card to give me access to the library. He led me to a desk containing a box file and various brown envelopes. Each one contained wonderful things (quite a personal sense of wonderful). Graham left me for a while and came back with notebooks and rolls of drawings..

Just a few hours to make a record of Sir Ian’s archive. This was what I had been hoping for. Here were his thoughts written in the notebooks, comments written in draft guides, and correspondence and manuscripts for articles and reports. The drawings showed plans and sections of his excavations. Very little photography though and there should be other drawings. I must make another trip in the Spring, not only for Chedworth but also to look at his excavation records for the Iron Age hillfort at Hod Hill in Dorset.

This felt like a great discovery and Sir Ian’s records will certainly be a guiding light during our future work at Chedworth.

Hod Hill: Camp Bastion, Dorset

One of the two Iron Age gateways through the ramparts of Hod Hill. The largest hillfort in Dorset. Perhaps Ptolemy's 'Dunium'

One of the two Iron Age gateways through the ramparts of Hod Hill. The largest hillfort in Dorset. Perhaps Ptolemy’s ‘Dunium’

Yesterday, we walked along the rampart and I asked the group to stop at the gate and look back and imagine. Beyond Stourpaine, the Dorset landscape faded towards the coast and Poole Harbour.

This is where they had landed and below us the soldiers were arranged into companies ready for attack. The scouts on the hill top, spotted the target and signaled its range and distance to the artillery and then.. it started, awful twangs and whirrings as an avalanche of ballista fell on the chief’s house and compound.

At least, this was Sir Ian Richmond’s story when he excavated the compound in 1956. How else to explain the Roman ballista bolts embedded in the walls and floors of the two round houses there, all angled and pointed in the same direction.

There are no cemeteries or massacre deposits of the war-dead here, unlike Maiden Castle or South Cadbury. Perhaps dismayed by the initial onslaught, they opened the gates and let them in. The round houses were abandoned, piles of sling stones and spear heads were found, left in the cupboards by the front doors. Perhaps the conquerors told them to go at once and leave all weapons.

We walked on along the north rampart and came to the point where Iron Age hillfort defences are severed by the straight lines of the Roman fort. Built in the highest place, with 360 degree views, to the best military design. The ditches laid out to lure attackers into a killing zone. Within javalin range. Easy to enter, difficult to leave. A bank and ditch across the entrance to prevent direct assault and then the narrowing of the causeway to the gate.

Part of David Stewart's geophysical survey of Hod Hill. Iron Age entrance bottom right. Roman fort edge top right. Note the trackways radiating out from the entrance between the dense concentration of round houses. The numerous black blobs are storage pits. The small groups of four blobs between the tracks are probably    post-holes for granaries raised on stilts.

Inside rows of timber barrack blocks in centuries, 500 men and then the larger long buildings cavalry units, another 300 mounted troops. The HQ building and hospital either side of the main road and across the way the houses for the commanders. The equestrian commander, of senior rank, had the bigger house (bit of friction there perhaps, Agricola mentions that infantry and cavalry often didn’t get on).

Here they were, 2000 years ago, in hostile territory. The nearest base about 10 miles away to the south. Bit like the wild west perhaps. Patrols, messages conveyed, supply trains attacked by the wild rebel elements.. perhaps. Who knows? The history is lost to us but from Vindolanda on Hadrian’s wall, we have rare letters that survive and from these we can imagine what it was like.

Where did these soldiers come from? A walk along Hadrian’s Wall is like a walk through the Empire. Each fort had a garrison from a different place but they carved the names of their cohorts on memorial stones. Perhaps from Spain or Syria, Tuscany or Gaul.

Hod hill is a great place to imagine, particularly in the Spring, particularly when the cowslips are out and the orchids are beginning to bloom.
