Castillo de San Juan Bautista
The Castillo de San Juan Bautista (Castle of John Baptist), also called Castillo Negro (Black Castle), in the city of Santa Cruz de Tenerife in the Canary Islands of Spain, was the second most important fort in the defense of Santa Cruz de Tenerife.
It is set in the heart of the capital, behind the Auditorio de Tenerife. It was built in 1641 and is located near the Parque Marítimo César Manrique. It has a round tower facing the sea. Each year in July a re-enactment of the Battle of Santa Cruz de Tenerife of 25 July takes place, which commemorates the unsuccessful attempt by the British Admiral Horatio Nelson to invade the city and the archipelago.
