A military bunker located near Havana, Cuba, associated with Camp Columbia, a historic U.S. Army installation constructed during the Spanish-American War and the Cuban War of Independence in 1898-1899. The site later gained significance during the Cold War era, particularly during the 1962 Cuban Missile Crisis when Soviet missiles were stationed in Cuba.
Archaeological research has uncovered graffiti in nearby bunkers and trenches along the Cuban coast, including defiant messages written by Cuban soldiers during the tense standoff, declaring that surrender was not an option.
