This rose-red-colored church is the only standing Byzantine church still in Greek hands. It's beside the giant redbrick building of the Fener Greek School for Boys, and while it's usually locked, it's still worth climbing up the hill to look at it from the outside. The church was the center of a nunnery refounded by the Byzantine princess Maria Palaeologina, who spent 16 years in Iran as the wife of the Mongol Khan Halagu in an attempt to form an anti-Muslim alliance.
