San Sebastian

On the East coast is the island's largest town, capital, port, administrative centre and home to a quarter of the native population. This sleepy little place still has some 15th-century Spanish colonial buildings including the Torre del Conde, a defensive tower intended to keep pirates at bay - unsuccessfully.

But its real claim to fame is as Christopher Columbus's last port of call on his trip to discover the Americas. The tourist office still contains the well from which he drew his water supply and the house that he later built here is now a museum.
