Welcome to the Urban Archaeology blog. Freelance archaeologist Chiz Harward provides a range of on and offsite services to the archaeological profession, including running and working on excavations, post-excavation services, training and development work, and illustration work. This weblog will carry news of projects as and when they happen as well as wider thoughts on archaeological issues, especially recording, stratigraphy and training.



Construction, demolition and recycling in the Cotswolds



We can tell a lot about the medieval buildings on our site at Horse and Groom Inn from the physical remains that survive, but there are also other clues to the appearance of the buildings, some of which can be inferred from what is not there, rather than what is.



Ten rooms make up our medieval building complex, forming two wings around a courtyard. Most of the walls are substantial –up to 0.8m wide and survive up to 1.3m high. They are built of local stone, with a foundation course of large stones at the base of each wall, and roughly coursed stones above. The walls are bonded using clay rather than lime mortar, an odd choice given that in the medieval period there was a large limekiln a few hundred yards uphill from the site.

The thickness of the walls suggests that the buildings were solely of stone construction rather than timber frames set on low stone walls, although some rooms may have had one or more timber framed stud-walls or partitions. Medieval documents relating to Bourton-on-the-Hill describe stone walls up to 3.6m high (12 foot), enough for a lower-ground floor with first floor above.

The doorways would have had wooden doorframes set into the walls, with the wooden doors mounted on iron hinges or pintles. The walls would have been bare stone –no fragments of medieval wall plaster have been recovered from the site. The walls may have been limewashed internally although no trace survives.

The buildings would have had timber roofs, fixed with wooden pegs and roofed with thatch or possibly wooden shingles. No fragments of Cotswold stone roof tiles have yet been found and although these expensive tiles would have been removed for reuse it is hard to believe that none would have been broken and discarded in and around the site. Similarly no earthenware tiles have been found on the site. Medieval documents record that some buildings in Bourton were roofed in stone tiles by the 14th century, but thatch was also used in the village.

The buildings had a variety of floor surfaces –fragments of stone flags indicate that some rooms were paved, in others just the underlying soil, bedrock or clay, whilst another had a floor of trampled stones. Scorch marks on some floors show that there were fires in the rooms, although only one formal hearth was found. Scorch marks on some walls suggest fire damage, whilst many stone blocks are partially scorched indicating they were reused from a building that had burned down.

The best-known Cotswold ‘deserted medieval villages’ are made up of a series of low earthworks formed when the buildings’ walls slowly decayed and collapsed to form low mounds. On these sites the individual building groundplans can be made out from the earthworks and whole villages can be mapped from the earthworks without the need for excavation.

At our site there were no such earthworks: before excavation the hillside was a gradual slope, and there were no visible mounds or depressions from the buried walls and rooms. The reason why only became apparent as we excavated: it is clear that the site was actively cleared and the buildings were all deliberately demolished, probably all at the same time. Someone clearly made a decision to raze the site to the ground, we don’t as yet know why but there may be a clue in the detailed records kept by Westminster Abbey who held the manor in the medieval period.

At first the buildings were cleared of anything that could be reused: the internal fixtures and fittings were ripped out and the stone flags were ripped up, the roof covering removed, and the roof timbers taken for reuse. The walls were then demolished working down from the wall-plate. Most walls were carefully dismantled –the inner and outer skins of facing stones were taken away for reuse whilst the smaller and less valuable rubble from the wall core was thrown into the centre of each room. As the walls were demolished downwards, so the discarded rubble rose upwards, and the demolition ceased when the two met leaving a flat level surface that gradually grassed over to leave no visible trace of the buildings.

Why the buildings were demolished may never be known, but it does tell us something about the end of the life of the complex. The materials from the buildings were carefully selected and taken away for reuse –this demolition did not happen at a time when there was no market for good building stone or when there was no labour available to move them; someone in a position of authority and with available resources made a decision, and the end of this site may have been part of the beginning of a new building or farm. Once we have fully recorded the walls we will dismantle the stones and they will be piled up for reuse in the new site, for some of the stone blocks that will be their third incarnation.
