Flanking the doorway are two Corinthian columns, while situated above it are two icons, one of Jesus Christ and the other the Holy Virgin.[1] The central sanctuary screen consists of ebony inlaid with crosses and squares of thin plated ivory.[3] The choir holds sixty-three icons made by Orhan Karabedian, while the nave contains a beautiful ambon consisting of mosaics which rest on fifteen columns.[3] The south sanctuary, which had been dedicated to Saint Gabriel, was converted into a baptistry, while the north sanctuary, decorated with ivory and wood, is consecrated to the Holy Virgin.[3] A stairway off the north aisle leads to an underground shrine.[3] Saint Barsum the Naked stayed here for twenty years, dying in 1317.[3] A service is held in the shrine on his feast day.[3]
