The town of Gallipoli is built partly on a promontory, 2 miles SW of Torre Sabea, and partly on a small rocky and chalky island close W, which is connected to the promontory by a masonry bridge. The town is divided into two parts. The old part of the town stands on the island with an ancient castle, Castello Revellino, on its E side. The modern part of the town, Il Borgo, extends for about 0. 6 mile along the promontory. It is dominated by a tall skyscraper.
