This is the Tower of Hercules near La Coruña, Spain--the northwestern tip of the Iberian peninsula. It may be the only ancient lighthouse still in use. It's possible that a Phoenician work preceded it, but we can be sure that a Roman structure lies at the core of this tower. The Romans built it sometime during the reign of Emperor Trajan (r. 98-117 A.D.), who was himself from an area that forms modern Spain. The Romans referred to it in classical writings as Farum Brigantium.
