In Trench 1, excavation inside the flanker continued to further reveal the inner circular wall. The wall appears to be continuous but is in disrepair to the south, adjacent to the entrance through the flanker wall. Interestingly, the inner “circle” of stones no longer seems to be perfectly circular and is distinctly straighter along its eastern section. Between the inner wall and the flanker wall an intriguing deposit has been uncovered which contains charred wood and nails, this has been photographed and planned and will be investigated tomorrow. Outside of the flanker, excavation continued to establish whether the flanker wall was built directly on top of the natural subsoil or built in a foundation cut made into the subsoil. No evidence of a cut was found and the wall appears to be built on a layer of probable natural subsoil.

In Trench 2, we extended by a metre to investigate the other side of the wall and to see what exactly the relationship between the wall and drain is. Upon removal of the sods and topsoil, we came down onto a rubble layer which was found in the rest of the trench, and this was planned. Tomorrow this layer will be excavated and we will hopefully find that our wall is continuing (fingers crossed!).

As for Trench 3, the plot appears to be thickening! Yesterday, we were beginning to get the impression that the geophysical anomaly that this trench was opened to investigate was the rubble. This was ringing true in the early part of today, as some of our volunteers removed the rubble revealed natural subsoil directly underneath. However, this afternoon, upon further excavation, it appears that some of the rubble was sitting above what looks like an L-shaped cut feature. Cormac made the tentative suggestion that this could be a sort of gutter feature for draining the water away from around a building. Tomorrow is going to be an interesting day in this trench too.
