Description.
The rear area is characterized by three high apses, the central only slightly larger. Only the northern one has maintained the original decoration with pilaster strips and small arches.
On the western side is the cylindrical tower which replaced the second square tower, crumbled in an unknown date. On the same side a forepart was added in the 13th-14th centuries with an ogival entrance.
The tambour, which protrudes from the centre of the construction, is in Armenian style.
The interior is on the Greek Cross plan inscribed within a square, with four huge columns, decorated with brick elements, supporting the dome.
