9. Svalbard Global Seed Vault, Norway
Granted, Norway is in the Northern hemisphere. But this location is not any location in Norway. The Svalbard archipelago is located in the Arctic Ocean, halfway between Norway and the North Pole. Which is already a good point as it is a way to escape the heat of war (no pun intended). But its most interesting feature is the Svalbard Global seed vault that ranks 9th in our list of safest places on Earth from nuclear fallout. This odd-looking building, built in a mountain, is a storage facility for seeds of all kinds. And a vault. So, it is safe to hide in there while you choose which seeds (the seed vault “represents the world’s largest collection of crop diversity”) to plant first and let grow to give you new crops.
