Islet 29 is exceptional both in terms of the irregularity of its plan and the remains of craft activities. The latter generated a dumping area in a nearby courtyard. It is filled with abundant small glass objects and scraps of bronze, which were often offered ex voto.
The presence of two skulls (without mandibles) in a room of islet 30 has not been explained. The proximity to the hypostyle hall and the dumping area of islet 29 indicates a religious association.
