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.
During the crisis, Fidel Castro and Che Guevara set up their headquarters there to prepare the defense of Havana from aerial attack.
The first battery on this site was built between 1797 and 1799, and was named for Juan Procopio Bassecourt y Bryas, Count of Santa Clara, the Spanish governor of Cuba from 1796 to 1799.
[2] Then on 13 June the Krupp gun fired on the protected (armored) cruiser USS Montgomery at a range of 9000 meters,[3] also without effect.
Following the Spanish–American War, US troops were billeted there and later a barracks was constructed, which was torn down in 1928 or 1929 to provide a site for the hotel.
