The Agia Sophia dates from the 8th century and is modeled after the Hagia Sophia in Constantinople (4th century), also still standing. Photos by Peg.
The Ascension is shown in the dome.
The church was converted into a mosque after the city’s absorption into the Ottoman Empire in 1440. Here you can see the remains of the minaret. You can see the arch in the Islamic style versus the Roman style which is rounded.
