The Ice Hotel of Sweden is the biggest hotel in the world that is built entirely by ice and snow. This hotel is the brainchild of two close friends who are specialized in Ice architecture, Arne Bergh and Ake Larsoon.

Situated near the North Pole, the hotel covers and area of 6000 sq meters and requires 300 tons of ice to build. When completed, the hotel features a bar, church, main hall, reception area and rooms and suites for over 100 guests to sit and sleep on blocks of sculpted ice in the form of chairs and beds. Beside the hotel, a chapel will be built also entirely by ice and snow.

This hotel can only be built at the temperature of -5 to -10 degrees Celsius. What makes it challenging is that there will only be 6 weeks to build the entire hotel and this process will be done every year.
