Bari's historic nucleus is on a headland reaching into the Adriatic Sea. Bari offers about a day's worth of sightseeing. This area has been built on for millennia, but most of the archaeology is buried under the cluster of narrow lanes which make up Vecchia Bari. This part of the quarter is famous for being confusing and visitors are almost certainly going to lose their sense of direction. Between the heart of the Old Town and the sea is Bari's most famous church, the 11th century Romanesque Basilica di San Nicola. Dedicated to St. Nicholas, commonly known as Santa Claus, it was specially built to house his remains, which still allegedly lie in the crypt.. The historical lanes have been cleaned up. Local people live their lives almost as open and friendly, with doors open, women making meals in the doorways and lots of comings and goings. It is obviously an area with a close community, perhaps living by their own law. Police officers continually offer advice on hanging onto your personal belongings but as long as you take care you should not experience any personal crime.
