The oldest structure in the city, the 12th-century church with buttresses attaching it to surrounding houses is located in the center of the citadel's maze of cobblestone streets. Inside the Pisan-Genoese church, look for the 3rd-century white-marble Roman sarcophagus and the Renaissance baptismal font. Walk around the back to see the loggia built above a huge cistern that stored water for use in times of siege. The 14th-century bell tower rises 82 feet.
