Castillo de Sancti Petri

The castle features an irregular layout with multiple defensive walls, watchtowers, and fortified structures positioned across a small rocky islet at the mouth of Sancti Petri inlet.

Originally constructed as a watchtower in 1610 during Felipe II's reign, the fortress expanded throughout the 17th and 18th centuries to protect the Bay of Cádiz from naval attacks.

The site holds remnants of an ancient Phoenician temple dedicated to Melqart, later transformed by Romans into a shrine for Hercules Gaditanus.

Visitors can access the castle through boat services departing from San Fernando or Chiclana de la Frontera, with guided tours available through a digital application.

The fortress contains sections from different time periods, including a 13th-century Moorish architectural style and 18th-century military engineering modifications.
