4. Svalbard Global Seed Vault – Norway
Halfway between Norway and the North Pole, there is a chain of small islands, and on one of those small islands, inside a mountain is the Svalbard Global Seed Vault.
A backup storage facility just in case there’s a worldwide disaster, it contains over a million seeds with the capacity to store over four times that.
You can go and see the entrance to the vault, but you can’t actually go inside the vault itself which is 100m inside the mountain.
