During the last week we have been excavating two pits in the area of the baulk through the Hope-Taylor excavation. One of these has proved to be quite substantial and associated with a broken stone socket used as a pivot, which we have now lifted. Working out what the socket was used for is difficult as we have few other features that we can associate with it at the moment. It likely held a door post that rotated in the socket so we should be looking for traces of a building in the vicinity. Hope-Taylor excavated to both north and south of the feature and there is what appears to be a construction cut for a timber structure in his records to the north of the stone. If we can prove that these two features were broadly contemporary we might be closer to solving the problem and identifying a new building.
West of the pits we are currently working on one of the more interesting features in the Hope-Taylor excavation. It’s a linear stone structure that lies along the west extent of his trench. Hope-Taylor called it his ‘lower pavement’ and it has been a recognisable part of of his excavation since we first uncovered it. We touched on it in the last blog on Trench 3, as we were looking to see if we could join this ‘pavement’ through the baulk to a series of stones visible in section. The ‘pavement’ is important because it is a long linear feature that extends for many metres along the west side of the trench. Importantly it represents a stratigraphic signpost linking Hope-Taylor’s excavated material back into our sequence via the section we drew of the baulk.
We have been looking at the ‘pavement’ feature itself and some characteristics seem to be apparent. Is this stone structure really a pavement/road or a structural foundation for a timber building. The fortress wall must lie within 6 to 8m of our trench edge, judging by the position of the current wall and the edge of the dolerite plateau, which certainly leaves space for a building or a road.
The lower pavement extends for 11m (assuming it is seen emerging from the baulk) but does not extend all the way to the north end of the trench or further to the south into the southern Hope-Taylor trench. This alone would seem to make the road interpretation problematic. Looking at the surviving Hope-Taylor records, and the feature in the ground, it seems that it is a discreet structure that does not quite extend to the western trench limit. This makes us think that it must surely be a structural foundation, not a road. It also contains a variety of stone from dolerite boulders to occasional dressed blocks of masonry and these must have been re-used from an earlier building. If our further investigation can define it turning right angles at each end then we will have proved it is a building. Frustratingly as the majority of the structure lies beyond our trench and under the standing castle wall we will have only a limited chance to go further and define is role.
