    Site Overview

    Sancti Petri near Chiclana is an underwater archaeological zone where Roman and Phoenician amphorae and anchors are scattered across the seabed, protected as heritage. The Bajo del Medio pinnacle above the site holds groupers, barracuda and bream, blending history with healthy reef life. Intermediate divers explore the area with care not to disturb the artefacts, and the clear Atlantic water makes it a unique dive. Sancti Petri is a fascinating mix of culture and marine life. The site rewards careful planning, good buoyancy and respect for Spain’s marine-protection rules, and remains a favourite among divers who value dramatic volcanic or Mediterranean scenery, historic wrecks and rich marine life across a long, varied season.
