Landmark
Svalbard Global Seed Vault
Deep inside a mountain, down beneath the permafrost, a vast artificial cavern, already dubbed the Doomsday Vault or a vegetarian Noah's Ark, was opened in 2008. It's a repository with a capacity for up to four million different seed types (and up to 2.25 billion seeds in all), representing the botanical diversity of the planet. Note that casual visitors are not welcome.
