Background
The Castle of Sancti Petri (Castilian: Piedras Santas) is a stronghold located in San Fernando, Province of Cádiz, Andalusia, southwestern Spain. Situated on the little island of Sancti Petri, the defensive fortification was once one of a series of forts that protected the inlet, Caño de Sancti Petri. Of irregular shape and in the Moorish style, it dates from the 13th century. During the 1st century, the Phoenicians settled on the island, founding a temple dedicated to Melqart, their god, . When the Romans arrived they dedicated the temple to Hercules.
