The front door of Norway's Alta Igloo Hotel would be indistinguishable from the rest of its snowy surroundings were it not covered in reindeer fur. Step through the door and the big freeze continues. A long corridor leads to a bar, chapel, gallery and 28 bedrooms; all are carved from ice. An other-worldly silence shrouds this Narnia-like land, where ghostly ice sculptures of wild animals are encased in or bursting through more ice and watery chandeliers throw diamond shapes against the milky white walls and blue-tinged ceiling. All will melt away when the temperatures begin to rise around April.Alta Igloo Hotel opens its door in January each year and melts away again in the spring.
