This winter marks the twenty-third chilly season for guests at Sweden’s ICEHOTEL, located in Jukkasjärvi. It’s the first and largest ice hotel in the world, erected in the early 1990s. ICEHOTEL started life as an igloo to host an art exhibition, and a serendipitous overnight stay sparked an idea. Since then, creator Yngve Bergqvist has expanded the structure to a massive getaway that constantly changes thanks to guest artists — and the sun, of course. Ben Rousseau and Ian Douglas-Jones designed the room pictured above, in anticipation of Tron: Legacy in 2010.
