This is one of two walls which create a kind of peristyle within the building/property we were excavating. Both walls abut each other and are constructed by cutting the tufo floow 1173, 1231, 1216, 1215 (which were one large floor originally). Also wall 1226 was cut into the tufo floor, so that there might be a contemporary relationship between walls 1186 and 1187 and 1226 - which marks a phase of reorganization of this property.
