Gallipoli is a coastal town in Apulia, southern Italy. The historic center, on an island off the mainland, shelters churches like St. Agatha’s Cathedral, with its ornate facade. Nearby, the Church of St. Mary of Purity has a maiolica tiled floor. Gallipoli Castle includes the Rivellino tower, standing apart from the main building. Across the bridge, on the mainland, is the Greek Fountain, dating from the Renaissance.
