The Santa Clara Battery, with its two remaining coastal guns, one a caliber 305mm (12") Ordóñez HSE Modelo 1892 rifle and the other a 280mm (11") Krupp, stands on the grounds of the Hotel Nacional de Cuba, in Vedado, Havana. UNESCO in 1982 included the battery[citation needed], together with Old Havana, in its list of UNESCO World Heritage sites. There is a small museum featuring the 1962 Cuban Missile Crisis in the battery. During the crisis, Fidel Castro and Che Guevara set up their headquarters there to prepare the defense of Havana from aerial attack. The museum is in tunnels there known as the Cueva Taganana (Taganana Cave), for the hill on which the battery stands.
