Tower of Hercules, probably the only ancient Roman lighthouse still in use, named for one of the most famous heroes of Greek and Roman mythology. The tower stands at the entrance of A Coruña harbour in the autonomous community of Galicia in northwestern Spain. A Phoenician tower may have occupied the site originally, but the present structure, 185 feet (56.8 metres) tall, is considered a Roman work dating from or at least remodeled during the reign of Trajan (98–117 ce). It was designated a UNESCO World Heritage site in 2009.
