Tower of Hercules
Sunday, 13th November 2005 by James Turnbull
The Tower of Hercules is the oldest Roman lighthouse in the world and the only one still in operation. Spanish legend has it that one of the many heroes named Hercules battled the giant GeriÃ³n on this site, killed him, and built the 68 metre tower on top of his bones (Ground level picture).
There is also what appears to be a strange purple orb in the satellite photo (top left of the thumbnail). I can’t find any mention of paving art or a reflective dish near the tower, so can only conclude it is a giant version of the 80′s office toy / science experiment, the “Plasma Globe“.
