The building is built of masonry made with bricks and stone.
It has a cross-in-square plan surmounted by a dome, with a bema divided in three parts and a narthex.
It is only 15 metres (49 feet) long, included the narthex.
The arms of the cross to the north and south are covered with barrel vaults, and the interior is lighted by triple windows.
Four columns with capitals sustain an octagonal drum, which bears the dome.
The three apses are semicircular.
The central apse projects outside, and is opened by a large window, divided in three parts by two pillars with capitals.
The diaconicon has been reused as mihrab of the mosque.
The prothesis is surmounted by a barrel vault.
The mosque has no minaret.

Before restoration, the building was in a very bad condition: the narthex was almost completely ruined, the columns had disappeared, and the paintings were barely visible.
The four missing columns have been replaced with ancient ones, whose origin is unknown.
The edifice has never been the subject of a systematic study.
