The Tower of Hercules is an ancient Roman lighthouse guarding over the Northern Spanish coast. At over 1900 years old, it's the oldest Roman lighthouse in use today and has been a UNESCO World Heritage Site since 2009.
Through the millennia, many mythical stories of its origin have been told. According to a myth that blends Celtic and Greco-Roman elements, the hero Hercules slew the giant tyrant Geryon after three days and three nights of continuous battle. Hercules then - in a Celtic gesture - buried the head of Geryon with his weapons and ordered that a city be built on the site. The lighthouse atop a skull and crossbones representing the buried head of Hercules' slain enemy appears in the coat-of-arms of the city of Coruña.
