Joint Defense Facility Nurrungar, Former defense ground station in the outback, South Australia, Australia.
The site sits quietly in the remote outback, surrounded by open land and low hills, with large plain buildings enclosed by high fences and barbed wire that create a sense of security and isolation.
Built in 1969 during the Cold War, the facility worked with satellites to detect missile tests and nuclear explosions, playing a secret but important role in early warning systems for Australia and the United States.
The facility represented the close alliance between Australia and the United States but also sparked controversy and protests, as many locals worried that its presence could make Australia a target during international conflicts and tensions.
The site was closed in 1999 and its functions moved to Pine Gap near Alice Springs, with most buildings now empty and stripped, though some areas are still occasionally used for military testing and remain protected.
A large white dome, called a radome, once covered a satellite dish and still stands on the grounds today, silent and stripped of equipment, surrounded by unused tennis courts and empty secure rooms that feel frozen in time.

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.
