Ice Hotel (Sweden)
A real masterpiece is erected here every winter, crafted each year by different artists.
There are many rooms that can be rented overnight and can be visited during the day. Those brave enough to stay overnight are issued with sleeping bags and spend a night in a room with a steady temperature just below the freezing point.
There is also an ice bar with famous vodka shot glasses created directly from the pure river water and a wedding chapel.
This is where the boom of hotels made of ice originated.
