House of Lusignan
The choir does have a surrounding ambulatory, but does not possess any apse chapels. This follows the plan of Notre Dame de Paris, which had in turn influenced a number of other cathedrals, including Notre Dame de Mantes at Archbishop Thierry's hometown. The transepts consist of chapels that have the same height as that of the aisles, and are attached to the second bays to the west of the ambulatory. This follows the plan of the Poitiers Cathedral, which is the episcopal church of the French town of Lusignan, the hometown of the House of Lusignan. The north and south entrances had initially been in the fourth bay of the nave, although the Ottoman-built Aziziye Gate is at the eastern end of the cathedral. The initial arrangement is thought to have been modelled after Sens Cathedral.
