These extensive and well-restored caves were used as a refuge during sieges, and pop out at a small beach below the cliffs. The Calle de la Concepción continues up to the baroque Iglesia de la Purísima Concepción and, just below it, the entrance to Las Cuevas del Conventico. A short film and guided tour (both in Spanish) detail the history of the caves and tunnels that lead to the cliff face. The Phoenicians first excavated the tunnels; later occupiers took turns enlarging them and they now extend over three levels. They are meticulously maintained and well lit, which sadly eliminates much of their mystery.
