According to the official website, over 1,000 tonnes of ice cut from the frozen Torne River and 30,000 tonnes of “snice” (a snow-ice mixture that that strengthens the building’s structure) were used to construct the hotel.

Each year since 1990, the Icehotel has grown in size, with a newdesign each time, reports IceHotel.co.uk. This season, it features 61 rooms including 16 special “Art Suites” designed by local artists, a bar, chapel and a movie theater.

Each room is considered a habitable art installation, writes MyModernMet.com, featuring unique, decorative carvings in the ice walls. Temperatures inside the icy rooms never get colder that -7ºC inside, no matter the temperature outside, but guests still take a ‘survival course’ on their first night at the hotel. According to the website, there are also “warm rooms” and saunas for guests to warm up in after an icy-night sleep.
