Bodrum Castle

This guide to Bodrum Castle traces its 1409 papal decree, which forgave sins in exchange for labor and drew knights, masons and laborers from England, France, Germany, Italy and Spain, each nation building and defending its own tower. It follows the resource-strapped Knights of Saint John as they turned to a nearby ruin, the shattered Mausoleum of Halicarnassus, one of the seven wonders of the ancient world, mining its marble reliefs to fill these walls. Look for the carved Amazon reliefs built face-down into the stone as you walk from tower to tower.
