This is not a town on the main trail for foreign tourists but it's no worse for that. It has long been connected with lace-making and there's an interesting museum.
The old part of the town is fascinating and it is still a minor port.
There is a disproportionately large Friday market.
The most interesting tourist sight is probably the Convento de Santa Clara, later a school for delinquent boys. You may need to knock but then a guide will take you for a tour. A small fountain in a courtyard is fed by a narrow channel from a very long aqueduct, seen stretching away into the hills.
