The Tower of Hercules () is the oldest extant lighthouse known. It has an ancient Roman origin on a peninsula about from the centre of A Coruña, Galicia, in north-western 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. The structure stands tall and overlooks the North Atlantic coast of Spain. It was built in the 1st century and competently renovated in 1791.
