What was in a Celtic roundhouse?

A Celtic roundhouse was a house where large families lived during the Iron Age. The walls were made of daub (straw and mud) with no windows, and the roof was made of straw, helping to trap heat while still letting the smoke from the central fireplace escape through a small hole in the top of the roof.

What were Celtic houses like?

The Celtic tribes lived in scattered villages. They lived in round houses with thatched roofs of straw or heather. The walls of their houses were made from local material. Houses in the south tended to be made from wattle (woven wood) and daub (straw and mud) as there was an ample supply of wood from the forests.
