The dwellings of ancient people were semi-dugouts or dugouts, that is, dwellings with a rigid, often domed frame, buried in the ground. In the warm season, the most common dwelling was a hut. During periods of sharp cold snap, people went to caves. Here they built light shelters and huts. Usually primitive people did not use the entire cave, but with the help of partitions they created their own dwellings.
For construction, branches, sticks, stones, animal skins were used.
