This remote Pacific island base stored chemical weapons, tested nuclear missiles, and housed a top-secret program called Operation PACER IVY. Located 750 miles southwest of Hawaii, the atoll was massively expanded through dredging to accommodate military operations.

After decades of environmental contamination, the U.S. military conducted an extensive cleanup before abandoning the base in 2004, leaving behind concrete bunkers slowly sinking into the rising sea.

Missile Site Radar

North Dakota’s flat landscape once bristled with nuclear missile silos, with this facility serving as their command center. Part of America’s anti-ballistic missile program, it operated for only 300 days in the 1970s before being shut down due to treaty limitations.

The massive concrete pyramid still stands in the middle of farmland, a Cold War relic that cost over $6 billion in today’s dollars but served almost no operational purpose.

This British Royal Air Force station in Somerset protected England’s southwest during World War II before being repurposed for Cold War defense. The base’s distinctive dome-shaped radar structures, known as ‘golf balls,’ monitored the skies for Soviet bombers until technology advancements made them obsolete.

Abandoned in the 1990s, the site has been partially reclaimed for housing, though several original buildings remain standing among residential developments.

Fort Ord

Once one of America’s largest military training centers, this California base prepared soldiers for combat from World War I through the Gulf War. Covering nearly 30,000 acres along Monterey Bay, Fort Ord housed up to 50,000 troops at its peak.

Closed in 1994 during post-Cold War budget cuts, parts of the base have become California State University Monterey Bay, while other sections remain abandoned with crumbling barracks and forgotten training facilities.

Known as ‘Little Moscow,’ this massive Soviet military city in East Germany housed 75,000 Soviet personnel and their families. Complete with schools, theaters, and the largest Soviet military hospital outside Russia, Wünsdorf served as headquarters for Soviet forces in Germany.

When Russian troops departed in 1994, they left behind everything from military equipment to personal photographs, creating a time capsule of Soviet military life now covered in decades of dust.

Teufelsberg

Built atop a man-made hill consisting of World War II rubble in Berlin, this listening station gave American intelligence a 360-degree view of Soviet communications. The distinctive white radar domes perched above the divided city intercepted Eastern Bloc transmissions throughout the Cold War.

Abandoned after the Berlin Wall fell, its graffiti-covered ruins have become both a tourist attraction and a symbol of espionage’s physical infrastructure.

Torpedownia Hexengrund

This concrete platform standing in the Baltic Sea off Poland’s coast once tested torpedoes for Hitler’s navy. Connected to shore by a now-collapsed pier, the facility allowed Nazi Germany to perfect underwater weapons in a controlled environment.

After World War II, it was simply abandoned to the elements, with waves gradually eroding its concrete pillars as seabirds make nests in former torpedo launch tubes.

These bizarre structures rising from the Thames Estuary like mechanical sea creatures defended Britain from German air raids. Built in 1942, these seven interconnected steel platforms housed anti-aircraft guns and radar equipment, shooting down numerous enemy aircraft.

Abandoned after the war, one fort briefly became a pirate radio station in the 1960s, while others slowly rust in the harsh sea environment, accessible only by boat.

RAF Upper Heyford

This sprawling air base in Oxfordshire hosted American nuclear bombers during the tensest years of the Cold War. Its hardened aircraft shelters and specialized facilities supported operations that kept nuclear-armed planes ready to deploy within minutes.

Closed in 1994 as the Soviet threat disappeared, parts of the base have been preserved as historic landmarks while others have been repurposed for housing and business parks.

Kadena Communication Site
