Spanish legend has it that one of the many heroes named Hercules battled the giant Gerión on this site, killed him, and built the Tower on top of his bones. This is why the Tower and skull-and-crossbones image is part of the coat of arms of the City of La Coruña.
According to Irish and Spanish mythological history, the Tower of Breogán was located on this site. Breogán was the brother of Mil king of the Ibero-Celts, and father of Ith, the leader of the first Ibero-Celtic expedition to Ireland. It was from Breogán's Tower that Ith first saw Ireland, 900 kilometres north of La Coruña.
They were big fat liars in those days too.
I climbed the 275 steps to the top and that is no lie.
