Martin mentioned earlier that the mosaic in the south corridor appears to run under the wall of the Triclinium or dining room. As he excavated, he noticed that this only happens in a short area then the mosaic run up to the wall again. We think that this might represent an earlier doorway which was then blocked up. In the picture, the doorway is indicated by a line of pink mortar under the wall, covered by about five stones in the lowest course.
This section of corridor has also revealed a curious stone feature which appears to have been dug into the mosaic. The feature has Victorian material in it. Only further excavation will tell whether this really is Victorian, or whether it is a Roman feature which the Victorians excavated then refilled.
As ever, if you have any ideas let us know!
