This incredible video gives us a sneak peek inside the world's first hotel made of ice as it marks its 30th anniversary.
The Ice Hotel was founded in 1989 by Yngve Bergqvist in Jukkasjärvi, in Swedish Lapland.
Every year it is rebuilt using 1,000 blocks of ice, each weighing 2.5 tonnes and each time it is kitted out by different artists.
This year, 33 artists from 16 different countries spent two weeks crafting the hotel.
The hotel features a bar and provides expedition-style sleeping bags so guests can sleep in the warm.
