Wall is constructed in courses of med-large rounded badsalt locally sourced in two faces with a rubble core packed with tiles and smaller stones. Mortar is used as bonding agent. The south end of the wall is marked by a large rectangular stone, a reddish conglomerate which does not appear to be local. Suprastructure probably pise, evidenced by high clay content in collapse and lack of large concentration of wall collapse (or stones were robbed out). Equal to 16003, foundations link up near center of area.
