Otranto, Italy's easternmost city, and Palascia's lighthouse, the symbol of this fact, divide the Adriatic and Ionian seas. Historic Otranto, with the imposing Alfonsino Castle and city walls, has a Norman Cathedral with Europe's largest mosaic floor inside, a UNESCO World Heritage site. The massacre of 1480 occurred in Otranto when Turkish soldiers executed the inhabitants. The nearby coastal areas hold beautiful sites: the Lakes of Alimini and the Frassanito Forest, Baia dei Turchi, Torre Sant'Emiliano, and Porto Badisco. Otranto is accessible by train and by car along highway 16 or provincial road 366 San Cataldo - San Foca - Otranto.
