Temple A Subterranean Structure 1

View of the "subterranean" portion of Temple A after initial excavation (date: January 2008). Note the arch and the spring of a vaulted substructure.

There is a substructure of the Temple of Zeus at Aizanoi where Cybele (the mother deity) was worshiped. [compare the vaulting of the Aizanoi substructure!]
