Now that the new
square is in the process of construction it has proved necessary to
empty and record archaeologically the cellar range at the Priory Road
end of the site that was first exposed in the archaeological
evaluation.
The
whole of this end of the site seems concerned with water management and
drainage. The largest "cellar" is rendered internally and seems to have
been used as a massive water tank. A drain in one corner allowed it to
drain into the smaller "cellar" adjacent via a type of wooden sluice
arrangement.
