An igloo translated sometimes as snow house, is a shelter constructed from blocks of snow, generally in the form of a dome. There are three types of igloo, all of different sizes and all are used for different purposes. The smallest is constructed as a temporary shelter, while out on the land or sea ice camped in one of these iglooit for one or two nights.Next in size was the semi-permanent, intermediate sized family dwelling. This usually was a single room dwelling that housed one or two families. Often there were several of these in a small area, which formed an Inuit village.The largest of the igloos was normally built in groups of two. One of the buildings was a temporary building constructed for special occasions, the other was built near by for living. A large igloo may have been constructed from several smaller igloos attached by their tunnels giving a common access to the outside. These were used to hold community feasts, and traditional dances.
