Are you the kind of person who likes staying in unusual places？ If the answer is "yes", th

en try the world's coldest hotel in Jukkasjarvi in the north of Sweden. But go in winter or all you'll find is a pool of water, because the hotel melts every spring!

The man who runs the Attic Hall Hotel is Nils Yngve Bergqvist. He built his first ice building for an art exhibition in 1991 and he designed the present hotel—over 200 meters square—himself. It took workmen about two months to pile 1,000 tons of snow onto a wooden base. As the weather got colder, the snow froze and then they removed the base. The whole building and everything in it are made of snow—except for the wooden front door. There's a theatre which Nils uses for a jazz club, a radio station and a large ice bar. As you can imagine, hot drinks are popular with the guests! The rooms have no doors; there's no furniture, no heating and everyone sleeps on ice beds. But the 800 people who stayed at the hotel this winter seemed to like it. If you want to stay in one of the ten ice rooms, it will cost you about ￡30 a night. You will receive a survival certificate from the manager.

When the winter's over, Nils holds his annual contest to predict the day that the hotel will fall. The person that guessed the day correctly last year receives a large painting from an ARTic Hall exhibition. Nils's ice hotel is becoming world-famous and he loves his work.. He's already excited about his next project — an ice hotel that will have more complicated architectural features and, he says, will be bigger and better.
