Minuteman Missile National Historic Site

This site preserves a Minuteman II missile within its launch tube, surrounded by underground bunker facilities that housed the control personnel. The structures date from the 1960s and display the technical systems used for surveillance and launch readiness.

The complex was built in the 1960s as part of the Minuteman missile program and kept nuclear weapons on constant alert for 30 years. Following arms reduction agreements, the facility was deactivated in 1991 and later preserved as a historical museum.

The site reveals how military personnel experienced daily life while monitoring nuclear weapons during intense Cold War tensions. Visitors can observe the confined working conditions and understand the psychological weight carried by those responsible for potential global destruction.

Visitors can descend into the control center and explore the underground chambers where officers worked their shifts. Wear comfortable shoes as there are steep stairs to navigate, and plan for several hours to see both the command center and the missile silo thoroughly.

The missile silo extends 80 feet (24 meters) underground and was engineered to withstand the blast pressure from a nearby nuclear explosion. This reinforced construction reveals the extreme precautions taken during the Cold War and how seriously military planners prepared for worst-case scenarios.
