Having removed the mortar floor surface in Trench 3 we have been trying to excavate the construction slot along its west side, as we previously excavated the one on the east side. It has proved to be very difficult to trace at times, but we need to excavate it to separate the finds from its fill from the finds within the layer that lies beneath the floor surface next to it.
We still have some questions unanswered, such as: Was there a construction slot on the south side? But having looked for evidence for this diligently for some time, and not being able to answer this question, its time to move on. We should see a new north west corner emerging next week.
