A military bunker located on the Cuban coast, associated with the 1962 Cuban Missile Crisis. During this tense period of the Cold War, Cuba hosted Soviet nuclear missiles, leading to a 13-day confrontation with the United States. Archaeological research has revealed graffiti inside this bunker system, including defiant messages from Cuban soldiers indicating their resolve during the crisis.
The bunker forms part of a larger network of defensive fortifications built along Cuba's coastline during this period of heightened military tension between the superpowers.
