Tower of Hercules

The Tower of Hercules is the oldest known extant Roman lighthouse. Built in the 1st century, the tower is located on a peninsula about 2.4 km (1.5 mi) from the centre of A Coruña, Galicia, in northwestern Spain. Until the 20th century, it was known as the Farum Brigantium. The Latin word farum is derived from the Greek Φάρος, Pharos, for the Lighthouse of Alexandria in Egypt. The structure stands 55 metres (180 ft) tall and overlooks the North Atlantic coast of Spain. The tower was renovated in 1791.
