The Tower of Hercules is an ancient Roman lighthouse on a peninsula about 2.4 kilometers (1.5 miles) from the centre of A Coruña, Galicia, in north-western Spain.
The name Corunna is said to be derived from the ancient column. The structure is 55 meters (180 ft) tall and overlooks the North Atlantic coast of Spain.
It is almost 1900 years old, was rehabilitated in 1791, and is the oldest Roman lighthouse still used as a lighthouse.
