Day 5: Understanding undercrofts and deciphering drains

Today has been another rain-affected day, with a very damp and bedraggled team making their way back to camp a little earlier than planned. However, things are still steadily progressing and there have been exciting developments in almost all the trenches. 

Trench N and P
Although the two trenches are separate, the building they share between them is causing much excitement between the archaeologists. In addition to the large number of glazed floor tiles from Trench P (see the blog entry for Day 1), Trench N has produced a rather lovely piece of anthropomorphic sculpture; a hand clutching an object which appears to be a book. Whilst fragmentary, it does suggest a high profile building originally stood on the site and supports our supposition that the two trenches are situated over the medieval hospital. Furthermore, the large mounds of masonry contrast sharply with the large depressions between them, which suggests the floor collapsed after the building fell into disuse. This raises the possibility that the building may have an undercroft, in which case our diggers have a lot of work in the weeks ahead! By early next week we should be in a position to remove the rubble and start to investigate the structure beneath.

Trench R
Trench R is proving to be a slight enigma. The trench is situated over a strong geophysical anomaly and clear earthworks, but this does not correspond with the current archaeology. The rubble, whilst linear, is not overlying any substantial structure and, once it has been removed, the trench will consist of a single sandy clay layer. Despite this slightly pessimistic outlook, the geophysical and topographic surveys still suggest there may be something lying underneath this and we hope to uncover this in the upcoming days.

Trench S

Finn, finder of the Trench S wall!
Careful excavation and removal of subsoil in Trench S has revealed another wall in the southeast corner of the trench. This appears to be the return of the wall we had uncovered originally, although unlike our first wall it is composed primarily of limestone rather than chalk. However, the junction of the two walls appears to have been robbed, with clear evidence of a robber cut containing small fragments of broken masonry (this is just in front of Finn's trowel in the photo). We are currently removing the rubble from either side of the original wall and by next week will be in a position to investigate this further.

Trench T
Trench T has a drain! As monastic drains are one of Francesca’s key interests, she is particularly excited about the find of a brick built structure with a vault in the extended portion of her trench. Although the vault has collapsed, it appears to be the outflow of a drain which continues as a rubble-filled depression in the south of the trench. We have a lot of work to do in the area surrounding the drain before we can start to carefully excavate this feature but, as drains are usually associated with disposal of household and human waste, we are extremely hopeful that the trench should produce plenty of environmental material as well as some sensational finds.

Despite the rain (which has just about stopped!), spirits remain high; the camp is currently filled with the sound of impromptu communal song and everyone is looking forward to a quiz which will begin shortly. The high morale is just as well, as we are already almost a quarter of the way through the excavation and there is plenty of archaeology still to uncover!
