Diybarbakır was once home to a large Christian population—Armenians, Chaldeans, and Assyrians—and several churches remain in the city, although the only one that still holds regular services is the Assyrian Orthodox Meryem Ana Kilisesi, on the western end of the old city. A peaceful oasis in the midst of the bustling city, the church is said to be built on the site of what was a temple used by sun worshippers and has a large courtyard lined with basalt stones. Parts of the church date back to the fourth century—look for the remains of the Roman arch beside the altar—but most of the structure is medieval. Services are held every Sunday at 8 am, although only a few people usually show up. Look for the signs from the Urfa Gate and be aware that this is one of the poorer parts of the old city.
