This wall may have been the final construction required to enclose room 14, given the presence of earlier techniques present in the room's other walls that are lacking in 7292 such as ashlar masonry. Additionally, 7293 appears to be a pillar base, likely one in a series extending southward, later incorporated into 7292. It seems likely that 7292 was completed with spoliated basalts, possibly from the same source or time as those found in 7286.
