Artist duo living and working in Stockholm, Sweden, Bigert & Bergström, have created an egg-shaped structure that lies in Luossabacken in Kiruna, Sweden’s northernmost town.

At first, the 'Solar Egg' just looks like a unique structure that was simply built to look pretty, however, you might be surprised to know it's actually a sauna - probably the best-looking sauna we've ever seen. Check out some of the shots of it below and head to Bigert & Bergström's website for more of their work.
