Svalbard Global Seed Vault, Seed vault in Longyearbyen, Norway
The Svalbard Global Seed Vault is a seed repository built into a mountain chamber near Longyearbyen in Norway, preserving genetic material from crop plants. The subterranean system consists of three refrigerated rooms located 130 meters deep inside the rock, maintained year-round at minus 18 degrees Celsius (minus 0.4 degrees Fahrenheit).
The repository opened on February 26, 2008, after construction began in June 2006. The facility was created in response to concerns that seed banks worldwide could be lost through natural disasters or armed conflicts.
The facility serves as a backup for seed collections from countries around the world, safeguarding the foundation of future food security. Although visitors cannot enter the interior, the importance of this work is visible through the illuminated entrance portal on the mountainside, which glows at night.
The facility is not open to visitors, as it was designed as a high-security storage space. However, you can see the illuminated entrance from the outside, which appears as a triangular concrete portal on the mountainside.
In 2015, seeds were released from the repository for the first time when Syria requested backup samples to replace material lost from a gene bank during war. The release followed exactly the procedures intended, proving that the system works when needed.

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.
