Viking long house with a stone-lined hearth in the middle. A fire was kept for cooking and heating and the smoke escaped through a hole in the roof. The hall was often smoky and smelly. The floor of the hall was made of hard-packed earth, covered with reeds or straw. There were long, wooden platforms along each side of the hall against the walls where people slept at night, using pillows and quilts filled with feathers or down, and blanket and furs to keep them warm.
