Slabs 8358 and 8400 prove that there were two different drainage features, likely at two different periods in this space. 8358, and 8400 prove that this drainage feature was linear running north to south and did not turn to connect with cut 8292 for a fistula. It is likely that 8292 was installed after the drain associated with 8358 and 8400 went out of use.

SU is probably linked to the drain feature that has appeared under floor 8352 and under the foundation of wall 8122 but whose excavation is still in progress.

cut associated to a few rocks bound w mortar put in place to possibly hold a fistula or water pipe bringing water underneath floor su 8352
