Viking homes called longhouses were simple log houses. Houses were usually one big, long, rectangular room with a central open fire, and a hole in the roof to let out the smoke. Homes had very little furniture. Benches were used for sitting, and also for beds. Wealthy homes might also have a table or two. For warmth and softness, fur rugs covered the floor, the benches, and sometimes the walls. Windows were placed in roofs and covered with thin animal skin. Archaeologists have discovered some Viking homes that had partitions that could divide rooms as needed. Unless the family was wealthy enough to have a barn, domestic animals were kept inside the house at night, which provided extra warmth for people and added protection for the animals.
