The prothesis and the diaconicon are represented by chapels to north and south of the apse.
The two smaller compartments and apses at the sides of the bema were sacristies, the diaconicon and prothesis.
Only the diaconicon now remains, covered by a cross-groined vault, and its apse pierced by a door leading to the hall of the Teké.
It is covered either with a barrel or with a cross-groined vault, and communicates with the prothesis and the diaconicon.
The prothesis and diaconicon have barrel vaults and apses with three sides projecting slightly on the exterior.
It has neither prothesis nor diaconicon of its own, but communicates with the original diaconicon of the main church.
The position of the prothesis and diaconicon in particular is identical in the two churches.
