Every year the Icehotel in Jukkasjarvi, Sweden is built anew during the months of November and December and then allowed to melt away after April. Each time, selected artists from around the world are invited to design and reconstruct the rooms of the famed hotel. Over 30,000 people make a stop at the Icehotel, while 15,000 international guests will go home experiencing what it feels like to sleep in an icebox, reports Design Boom.

For its 25th year, Maurizio Perron, a sculptor from Italy, Vitcor Tsarski, an architect from Bulgaria, and Wouter Biegelaar, a Dutch product designer, teamed up to create the hotel’s icebar. What resulted is an explosion of snow and ice in the heart of the building. Shards of crystal ice form the bar and chairs for the hotel’s speakeasy, while contrasting soft, expressive waves of snow become wall decorations. The collaboration between the three artists is titled BOOOM!

This year, the Icehotel will feature 16 artist-designed suites, a bar, and a theater made of 1,600 tons of snow and ice.
