St Catherine’s Chapel,

A cremation pot cemetery, probably Romano-British

and a non-existent Roman fort

AHRP’s geophysics programme 2006

The Abbotsbury Heritage Research Group is surrounded by tantalising archaeology, but we are mostly too old to enjoy digging. In any case, digging is slow and very expensive since the finds have to be cleaned, identified, drawn, written up, published and conserved. Very few amateurs can do all this competently, so it is essential to employ real archaeologists. Any dig that does not go through these stages sets archaeology back rather than forwards since it destroys evidence that later generations may find useful without adding to the record.

When we began our project we were earnestly asked by the local professionals not to find anything but the most nationally important artefacts. And, so far, we have done just what they asked.

Bearing this in mind, and since many of us have a technological cast of mind, we thought that we would spend our money on non-intrusive electronic surveys since these could probably tell more of whatever story there might be at a fraction of the cost and effort of digging the same area. Of the several companies who offer archaeological geophysics we chose Archaeophysica – www.archaeophysica.co.uk who did a very good job for us.

In 2006 we decided to investigate three sites:

An otherwise unremarkable field with an old grass track across it. Dog walkers had for years found pot sherds there. The author of this note once found a fine piece of Samian ware – Roman army officers’ mess stuff - among the clods. At Easter 2005 we organised a field-walk. Each of the 80 artefacts found was individually labelled and bagged and its GPS position recorded. When these positions were plotted on a large scale OS map using Mapmaker software, an interesting cluster was found in the centre of the field. It was very near some soil marks that had shown up in a black and white vertical photograph taken in 1968. When they were completed, the geophysical results were surprising and showed what has been interpreted as a Romano-British cemetery of cremation urns with a paved road running through them.

 

The illustration shows the magnetic data plot laid over the Ordnance Survey map. Our field walking finds are plotted as dots. The track runs left to right through the lower part of the plot. The supposed cremation urns are visible in the bottom part of the plot as neatly arranged black dots. The black area above the track might be the site of the cremation fires. There are probably other urns in the upper part of the plot.

In late March ’07 we spent the last of our grant money on a one-day dig of one of the pots in the small group at the lower left of the surveyed area above.

The archaeologist Nico Vaughan (http://www.nicovaughan.co.uk/) did the job for us. We wanted to prove that it was a burial, to get some dating evidence and to get an idea of how badly the ploughing had damaged the archaeology.

Archaeophysica came along to survey us into the right spot on the ground. Ordinary GPS has an error of about 5m. That would mean we had to dig about 40 sq m to have an even chance of finding the pot we were looking for. And that would take more time than we could pay for. Luckily they were able to use the European Geostationary Navigation Overlay Service (EGNOS) which gives an accuracy of about 1 m. This is a European version of the American WAAS system A number of ground stations are spread over the landscape. Each one knows where is it. It compares its true position with its current GPS position and broadcasts a correction via a geostationary satellite. This worked well, and it turned out, after some energetic shovelling, that the hole we were looking for was just 1m from the spot predicted.

We all had a clear idea of what would be found: the bottom of a big black pot, the rest ploughed away and perhaps a thin layer of burnt bones left in the shattered bowl.

As so often in archaeology, what we found was quite different. Bed rock –an inhospitable layer of limestone cobbles - appeared at only 30cm. Our pit turned out to be two pits, one dug into the fill of the other. The earlier one went down nearly a metre below today’s surface. We weren’t able to excavate it all, but we found a piece of pre-Roman pottery and a large animal bone sticking out of the section. There may well be a human skeleton further down, but we will not know till we dig further down.

The pit looking east. It probably goes another 30cm down. The layer of stones seems to show the top of the first hole; the earth above is the bottom of the fill of the second. The pre-Roman pottery fragment is just visible at the bottom left hand of the shadow.

We found the tibia of some small animal, perhaps a deer, which had a rough hole drilled through one end. It might have been part of a necklace. It was radio carbon dated by the University of Kiev to 180AD.

St Catherine’s Chapel and its platform at the top of the little hill to the south of the village.

St Catherine’s Chapel from the south

The Chapel enclosure is the darker green square

The look of the miniature cathedral, solidly planted on its terraced platform suggests that it is the heir to a much older religious tradition.

The Abbey was founded in 1024 by King Canute's thane Orc (perhaps he was one of the courtiers who stood damply round the great man’s throne while the tide rose) Orc was given a grant of land at Portesham and the charter survives. Presumably he was also given Abbotsbury, but it is likely that this charter was blown up with the house in the Civil War.

St Catherine of Alexandria first appears in history around 800AD. She has no solid historical basis and seems to have been the result of a re-branding exercise by the monks of St Catherine’s monastery in Sinai. Before that, the monastery’s major treasure was the bush from which God spoke to Moses – which still grows luxuriantly within the walls. This interesting establishment has survived to the present day because the monks still have a note from Mohammed requiring Muslims not to attack it. It is interesting that Orc’s wife Tola came from Rouen, the European centre of the cult of St Catherine and she may have brought the saint with her to Abbotsbury.

All this happened some 500 – 700 years before the Chapel we see today was constructed, and suggests that it replaces some earlier christian church which itself may have been converted from an earlier pagan temple. This was the economical practice of St Augustine’s missionaries who would, if the building were sound, move the old gods out, move theirs in and continue with the same congregation.

We asked the geophysicists to look for any signs of an earlier structure on the site. They used ground penetrating radar inside the chapel, on the platform round it and on the hilltop to the south. They found little to support the idea of an earlier temple, but on the other hand the platform seems to have been so thoroughly prepared that any trace of an earlier structure could well have disappeared. There was no evidence of a building on the hilltop to the south.

But - the Romans in Dorset seem to have tidied some old temples into neat square buildings in neat square enclosures. There is archaeological evidence at Maiden Castle, Jordan Hill Weymouth, Badbury Rings and Dewlish (see Bill Putnam, Roman Britain, 2007, p121-125). These structures do not seem to be aligned on any particular bearing. The temple building at Maiden Castle is about 19' square. The eye of enthusiasm might see the S corner of one of these aligned NW/SE in in radar traces 14,15,16.

A more robust interpretation of the radar results suggests that the site was cleared and the Chapel built as a single project. Until recently the accepted date for the building of the Chapel was the second half of the 1300s but by then the Abbey was deep in debt and the Black Death had reduced the available labour force by a third or even a half so such an elaborate building project seems unlikely. A somewhat earlier date seems more probable and, for the same reasons, this would apply to the architecturally similar Tithe Barn as well.

For its period the Chapel is fairly conventional. The aligned north and south doors allow for processions to pass through the building in an orderly way. The purpose of the project was probably to attract paying pilgrims and it is likely that they would have been shown the Abbey’s relics of St Catherine as they shuffled past.

The Chapel is laid out on what was probably planned to be a circular or egg shaped plot which would have been normal for the period. A curved edge is visible on the ground on the north side (the far side in the photo above) and curved edges to the east and west but it wasn’t finished to the south.

The radar survey shows what are probably graves under the grassy area immediately to the south – and this was the most desirable place to be buried because the north side of any church is the haunt of ghosts and evil spirits. There is a substantial radar reflection south and a bit west of the south door which is interpreted as the base of a stone cross. in radar trace 20. Since this is about a foot below the ground it might have antedated the building of the Chapel. It was the practice of the Minster priests to preach from a cross

Inside the Chapel, the foundations of the altar and brackets for two statues on either side of the window at the east end can be seen. The statues and altar were probably broken up and removed at the Reformation in the early 1500s. A statue of St Catherine in the chapel at Forde Abbey was smashed at the Reformation and thrown in a ditch. A few years ago it was found again and repaired. Our statue of St Catherine is probably in Abbotsbury somewhere and AHRP would like to find it.

The Abbey and its lands were sold to Sir Giles Strangways by Henry VIII in 1541. It is somewhat odd that the Chapel was not pulled down with the Abbey Church as the contract of sale stipulated. It is usually supposed that it was left standing as a sea-mark, but from any distance out to sea it blends into the hills behind and is almost invisible. In heavy weather it would be useless. Any big ship that came far enough into Lyme Bay to see it would already be in an extremely parlous position on a notorious lee shore. The Chapel is some use to inshore fishermen in helping them find the small reefs and weed patches that shelter particular fish, but it is hard to imagine that the King would bother about their convenience.

St Catherine is one of those embarrassing saints who have no documentary reality. She was huge during the middle ages, but after the Reformation and the counter-Reformation she fell into neglect. By the time of the Civil War in 1650 the Chapel had probably been abandoned as a religious site. The floor in the doorways show deep grooves which suggest that the building was used for a long time as a byre for cattle. There is a story in the village that a heifer once climbed the corner stairs up to the little room at the top and took a deal of getting down again.

In the aftermath of the Civil War there seems to have been an understandable revulsion from religion and its works. Many churches fell into disrepair (which is why Victorian rebuilds were often so drastic). By the mid 1700s the building needed complete restoration which was done by the then Lady Ilchester. St Catherine was removed from the Roman Catholic Calendar in 1967 on the accurate but irrelevant grounds that she was omnina fabulosa – a complete fable. The Chapel is now used for occasional informal CE services. And many people still visit it to leave touching notes and small offerings, asking for the saint’s help in the problems of their lives. If invoked by a spinster with the proper rhyming prayer she will produce a husband. This is only to be done in desperation since the results, in our experience, are usually no better than adequate.

Chesters Hill A crop mark in a photograph, taken by a Sea Harrier of the Indian Navy in 1988, irresistibly suggests a small Roman fort.

A contrast enhanced version of the photograph.

Chesil beach is the while area to the left, the Fleet

is the dark vertical stripe, mid-left.

The dark area to the right is grass. The ‘roman fort’

is in the upper central part of the picture

It stands on the lower slopes of Chesters Hill, on the edge of the Fleet, just to the SE of the Swannery. The fact that the site is called ‘chesters’ made the identification so certain (since castra, the roman word for a fort, often survives in modern place names as ‘Chester’) that we almost didn’t bother with the survey. But we did and we found nothing.

Striking absence of Roman fort

We spent some time wondering what had gone wrong. One bad omen, visible from the start, but ignored by all concerned was that our 1,800 year old archaeology was neatly framed by a modern fence (this fence has since been removed, but can still be traced on the ground). This is fine if there is something visible on the ground that needs protecting, but that was not the case here. A second possible factor, discovered by Max Warwick a couple of days before the survey team arrived, was the stranding of the Dorothea in February 1914. (see www.soton.ac.uk/~imw/cheslode.htm)

Dorothea in trouble on the Chesil beach.

This small cargo ship went aground on the Chesil just opposite our site on 14 Feb 1914. She had a cargo of magnetite (iron ore) which had to be shovelled out onto the beach before she could be refloated two years later. One would imagine that the ore - even more valuable in 1915 - 16 because of the war raging across the Channel - was transferred to barges in the Fleet, taken down to Portland and reloaded into a ship; but it could have been taken across to our field and stacked in neat rows on the grass for eventual removal by road. That could explain the modern fence and perhaps the cropmarks. However, it fails to explain the clear absence of any meaningful pattern in the magnetic survey.
