10 Most Insanely Protected Homes On Earth
9. Svalbard Global Seed Vault
Granted, no people actually live inside the Svalbard Global Seed Vault on the Norwegian island of Spitsbergen. That doesn't stop the place from being one of the most heavily-fortified buildings around though, and it is home to something that could feasibly keep millions alive in the event of a global food crisis.
Around 4.5 million seed samples (approx 500 seeds per bag) are housed in the facility. The reason human beings don't find the place habitable is due to the low temperature. Seed samples are stored at -18 °C, and oxygen levels are also kept low to delay the ageing process for samples.
A dedicated workforce who maintain the facility and work in the building's warehouse do stay nearby though, so technically this one counts as a home base for humans too. The Arctic archipelago location, borderline-hidden entrance, tight security measures and wild weather surrounding the facility make it nearly impossible to infiltrate undetected.
