The Royal Norwegian Navy has put up a secret, mountainside submarine base for sale... and judging by what it looks like, it would work both as a superhero hideout and as a supervillain lair.
The full above-ground space measures 13,500 square meters, including the opening at the side of the mountain. It's the 25,000-square meter space within the mountain that makes it oh-so-interesting, though. While you'll find mundane rooms like ordinary offices inside the property, it also has a dry dock for submarines and boats as well as a tunnel system, because no hideout or lair is ever complete without them.
