RAF Menwith Hill, Military intelligence station in Harrogate, England
The base sits on open land in North Yorkshire, where tall white domes shaped like giant golf balls stand out against the green countryside and protect sensitive satellite equipment from the weather all year round.
Built in the 1950s during the Cold War, this site began as a small listening post and grew over the decades into one of the largest intelligence stations outside the United States, expanding its role in global communications monitoring.
The white domes have become a local landmark and a symbol of secrecy, often appearing in debates about privacy and surveillance, while nearby residents continue to organize peaceful protests questioning the station's activities and lack of transparency.
The base operates around the clock with hundreds of British and American staff who work behind secure fences, and the site includes its own small community with a bowling alley, general store, and fast-food restaurant for personnel living there.
This station is part of the ECHELON network that intercepts communications from space, and its 33 radomes create a surreal contrast between the quiet rural landscape and the high-tech intelligence work happening just out of public view.

This collection brings together underground military sites, strategic bunkers, and highly secured installations across the world. Many of these places were built during the Cold War, when nuclear threats pushed governments to create protected command centers deep under mountains or in remote areas. Some remain active today, serving national security purposes, while others have been decommissioned but preserve their massive concrete structures and tunnels. Though their existence is known from public sources, access remains strictly forbidden. The sites include the Raven Rock Mountain Complex in Pennsylvania, carved deep into the Appalachian Mountains with tunnels stretching for miles through solid rock, and the Cheyenne Mountain Space Force Station in Colorado, where rooms rest on massive springs inside the Rocky Mountains to absorb shocks from potential attacks. In Russia, the Skalisty submarine base serves nuclear submarines through underground piers carved directly into rock along the Barents Sea. RAF Menwith Hill in North Yorkshire spreads across a wide area marked by white geodesic domes that protect satellite antennas, while the Svalbard Global Seed Vault lies embedded in arctic permafrost, storing millions of plant seeds behind thick concrete walls. These places show how governments sought to protect command systems, military operations, and even biological reserves by building deep into mountains or along remote coastlines, creating installations that remain largely hidden from public view.
