Description	A stone wall on a north south axis, extending from the southernmost extent of the bedrock cut of the cistern to the south (interior) face of the south wall (Locus 10) of the cistern. It seems to be a support element built in conjunction with the cistern’s south wall, and creates two separate niches behind the arches of the south wall. On its west face is a break in its plaster coating through which can be seen the underlying stone construction. The stones are far apart, suggesting that it is of relatively poor construction (much like the south wall) and relied on plaster for much of its sturdiness.
Size	1.14 m in north south length (on either side)-by-1.43 m in depth (to top of fill on east side) and 1.94 m in depth (to top of fill on west side).
Stage	Stage 2
Location	Behind south wall (Locus 10) of cistern, between niches (Loci 11 and 12) to south of arches (Loci 8 and 9).
Relations	Runs up to: Locus 4, bedrock, on ceiling.
Underlies	Locus 4, bedrock.
Definition	North south wall separating niches behind south wall arches of cistern
