It has been a busy but productive excavation season and, as always, seemed to come to a close all too soon. Thankfully it seems very likely that one of our principal objectives for the summer, which was to identify a building, or buildings, associated with our large and impressive-looking cobble surface, was fulfilled. We had been looking for post-holes or beam slots of a series of modest to small buildings that would front onto the cobbles. This was based on the metalworking building/forge that we had seen in a later (9th century) layer, that was build alongside a pebble pathway. It was quit a modest-sized building and, as we were looking for other industrial style workshops, it made sense that they would also be quite modest in size. As is often the case in archaeology, what actually was found turned out to be a little different. Instead of a series of smaller structures, we have now identified a large building at least 9.6m north-east to south-west. It extends beyond the trench towards the sea and as we have only seen clear evidence of two of the walls, we are far from certain about its width.
Rather than seeing evidence of the building itself, what we found was that the edges of two cobble and pebble surfaces align at 90 degrees (a right angle, like the corner of a rectangle) and therefore appear to outline the space where two sides of a structure once stood. As we only have its outline in general so far, we are still uncertain if, like the later 9th century one, it was associated with metalworking or some other industrial style activity. It does include in its floor space a hearth and stone-lined water channel that was uncovered by Hope-Taylor, but it seems likely that this is an earlier phase of activity so not evidence of what our newly discovered building was for.
This year we were also fortunate to have a donation to fund some radiocarbon dates, and we used them to confirm the date of the cobble surface and some potential associated features in the main section that passes through the Hope-Taylor area. As this is an important–and very likely deliberately-planned–surface, being able to more closely date this will help to interpret it better, and, just as importantly, interpret the features and structures associated with it. This new dating has confirmed that the cobble and pebble surfaces that outline two sides of the large timber structure discussed above are of the right date to be contemporary and are mid-7th to mid-8th century.
In addition to investigating the cobble surface and the features around it, we have also been looking at the west trench edge and Hope-Taylor’s ‘lower pavement’. We have long thought this was likely to be the foundation for a substantial timber building or structure rather than a pavement and further work seems to have confirmed this. Last year we thought that we found a southern limit to it, and this year we have further investigated what appeared to be gaps spaced along its length. We thought these might be indications of post-holes for raking supporting timbers (think of them as buttressing the main structure on a diagonal), but as no post-holes were found, we are now thinking that we were looking at this the wrong way! Perhaps we have a series of extensions from the line of the stone foundation and not pits cut into it. If this is so, then we still have raking supporting timbers, but they are based on extensions to the surface and would be more consistent with the main wall which must be a beam or series of posts set onto the slab stone foundation.
It is a little annoying when a blog tells you to keep checking as we have some important announcements to come, so I feel I should apologise for doing this now! The truth is we do have some really exciting projects for the next few months, but are just not quite in a place to announce them yet. It does mean though that the blog will be a good bit more active this autumn and winter than it normally is, which I hope is good news.
