This is the Church of St. Titus -- said to house the holy relics of it's namesake. Like other churches here, it was first built in during the Byzantine period. The Venetians used it as a Catholic Cathedral. The Turks transformed it into a mosque, altering one more time the church’s architecture. After earthquakes destroyed it in 1856, locals rebuilt it on its old foundations in 1872 but turned it into a Greek Orthodox church.
