Who invented the igloo?

The Inuit, also known as the Eskimos, are said to have invented the igloo. The Inuit used igloos as hunting and fishing camps for their men traveling far from home on expeditions. Igloos were easy to build and did not require a lot of energy or time.

Igloo blocks are made from a specific type of snow that is packed tight to guard against strong winds. The blocks are easy to cut and are lightweight. An igloo protects and insulates those inside it by blocking the wind and trapping body heat. Within a few days of use, an igloo can begin to turn into solid ice as the sun melts the snow and it refreezes.
