This year marks the 25th anniversary of the IceHotel art exhibit in Sweden. Each year, in the town of Jukkasjärvi, artists and architects work together to build some of the most beautiful ice hotels in the world. Complete with suites and lobbies, these ice hotels are pretty cool…literally! And the best part? Visitors are welcome to sleep the night. Of course, it is highly encouraged that guests don thermal wear and bundle up well because the temperature inside is a constant -7C! But no worries, you’re actually sleeping on a block of ice covered by a mattress and deer skin – so it’s all good! Check out these incredible works of art and plan your next trip to Sweden!
