A military bunker located on the Cuban coast, associated with the tense events of the 1962 Cuban Missile Crisis. During this Cold War confrontation, Soviet medium-range missiles were stationed in Cuba, prompting a U.S. naval blockade and bringing the world to the brink of nuclear war. Archaeological research has revealed defiant graffiti inside the bunker system, likely left by Cuban soldiers, declaring that surrender was not an option.
The bunker forms part of a network of defensive fortifications built during this period of heightened geopolitical tension between the United States and the Soviet Union.
