Every year, the town of Kemi builds the Lumi Linna, the snow castle. Composed exclusively of snow, the atmosphere is unreal; the lighting effects from the decoration add to this very unique atmosphere. The Lumi Linna has a restaurant with Finnish specialties and more than thirty rooms to accommodate visitors for the night. Inside, the temperature is -5°C. If you do not have the courage to sleep there, at least go and visit.
