Known as the 'Pearl of Puglia', beautiful Trani has a sophisticated feel, particularly in summer when well-heeled visitors pack the array of marina-side bars. The marina is the place to promenade and watch the white yachts and fishing boats in the harbour, while the historic centre, with its medieval churches, glossy limestone streets, historic Jewish quarter and faded yet charming palazzi is an enchanting area to explore. But it's the cathedral, pale against the deep-blue sea, that is the town's most arresting sight.
