While initially these blocks appeared to be a kind of buttress for wall 7078, upon further excavation of Room 3 and cleaning to the west of Room three, the line of ashlar blocks 7143-7144-7158 was discovered, in line with these blocks. Thus it appears that originally these blocks either formed a continuous wall running E-W, dividing the space between walls 7078 and 7142 into a smaller room. It cannot be determined yet whether walls 7158 and 7097 connected, or whether there was a doorway between them.
