The Castle of San Sebastián (Spanish: Castillo de San Sebastián) is a fortress located in Cádiz, Spain, at the end of La Caleta beach on a small island separated from the main city. It was declared Bien de Interés Cultural in 1993. History According to the classical tradition of the location of the fortress, there was a Temple of Kronos, a Titan of the Greek gods, the father of Zeus, Poseidon, Hades, Hestia, Demeter and Hera. In 1457, a chapel on the island was raised by a Venetian boat crew recovering from the plague. In 1706, a castle was constructed, which resulted in a fortified enclosure of an irregular plane. It defended the northern flank of the city from attack. At the base of the lighthouse was a watchtower from the Muslim period. In 1811 the Maltese navy arrived with the famous POW/rebel Junta of Buenos Aires, Juan Bautista Azopardo. He was housed in the fortress until 1815, when they suspected a leak and transferred him to the military prison in Ceuta. In 1860, a levee was built to serve as a link between the island and the city. The lighthouse has an iron structure designed by Rafael de la Cerda in 1908 and is the second electric-powered lighthouse in Spain. The tower rises to 41 meters above the sea. The Castillo de San Sebastian was declared a cultural landmark in 1985. References Bien de Interés Cultural landmarks in the Province of Cádiz Castles in Andalusia
