Trench One’s sunken featured building slowly reveals its secrets

The SFB under investigation

The SFB under investigation

Regular readers of the blog will recall that we have been investigating a sunken feature building (often called an SFB for short) in the south east corner of Trench 1 Some new evidence for our ellusive sunken featured building within Trench 1). Its broadly rectangular shape is formed from a shallow hollow in the ground, very likely the result of a deliberate structural cut, filled with a grey-brown silt with a substantial stone content. SFB’s are common on early medieval sites, but tend to be found on subsoils such as sands and gravels, that are easy to dig into, rather than the much more intractable stony boulder clay we have at the base of Trench 1. This makes us a little cautious about our interpretation of the feature at the moment and we would not be surprised if further investigation leads to new twists in the story.

Earlier we identified, what we believe to be a socketed stone that was well sited to be a central roof support. This interpretation of the stone’s final role appears to be still valid, but further investigation has revealed that its a broken, or roughed out, upper stone of a rotary quern. In addition we have two sherds of pottery associated with the feature. Both have an incised decoration on the outside of what is a course fabric. At the moment we are assuming that these sherds are early/middle Saxon in date. Hopefully the decoration will allow a specialist to date them a little closer than we can at the moment.
