Castle of San Sebastián

The Castle of San Sebastián sits on a small island connected to the mainland by a stone causeway at the northern edge of Cádiz. The structure features fortified walls and a distinctive lighthouse that rises above the surrounding seascape.

Construction of the fortress began in 1706 to strengthen the northern defenses of Cádiz against maritime attacks. The site had served a religious purpose since 1457, when Venetian sailors established a chapel there.

The site held religious importance for sailors, with Venetian mariners establishing a chapel in 1457 and carving their city's coat of arms into the stone.

The fortress can be reached daily via the Fernando Quinones footpath that connects from the La Caleta beach promenade. The causeway is well maintained and easy to walk, making it accessible for most visitors without difficulty.

The lighthouse was built in 1908 and was one of Spain's earliest electrically powered navigation beacons. This technological achievement made the fortress an important landmark for ships approaching the coast of Cádiz.
