The body of the church, which has five aisles, is principally Perpendicular.
Deep, there being a central avenue and ten aisles on either side.
"Gynaeconitis" is the term given by Procopius to the space reserved for women in the Eastern Church, and this separation of the sexes was maintained in the early Christian churches where there were separate entrances and accommodation for the men and women, the latter being placed in the triforium gallery, or, in its absence, either on one side of the church, the men being on the other, or occasionally in the aisles, the nave being occupied by the men.
The interior of the mosque is square and is divided into aisles by columns joined by Moorish arches.
The interior is in the form of a basilica, the double aisles being borne by ancient columns, and contains ambones and a candelabrum of 1311, the former resting on columns supported by lions, and decorated with reliefs and coloured marble mosaic. The castle at the highest point of the town was erected in the 14th century.
