E-W running wall made of large gray tufo ashlar blocks that serve as both foundation and first course of wall. Preserved only to first course. Truncated on W and possibly part of N by drainage channel 2206 and on E by unknown action. Possibly related to 2 c. BCE house, but relationship is not clear b/c of truncation on W. Block on E made of harder orange tufo that may belong to a different abutting wall, but aligns with gray tufo blocks of rest of wall and not enough preserved to tell for sure.
