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 Corunna.
Another legend embodied in the 11th-century Irish compilation Lebor Gabála Érenn— the "Book of Invasions"— King Breogán, the founding father of the Galician Celtic nation, constructed a massive tower of such a grand height that his sons could see a distant green shore from its top. The glimpse of that distant green land lured them to sail north to Ireland. According to the legend Breogán's descendants stayed in Ireland and are the Celtic ancestors of the current Irish people. A colossal statue of Breogán has been erected near the Tower.
