This building is based on the layout of a round house from the Moel y Gerddi site in the parish of Llanfair, Wales. At 33ft (11m) in diameter, it is the second largest round house constructed at Butser and is built on a double ring of posts. The interior is furnished and decorated to a high standard, circa forth/third century BC (middle Iron-Age), to give an experience of what life was like in pre-Roman Britain. It has a central fire place of flat stone slabs, in a shallow depression, covering an area of about 1 sq. meter. The original Iron Age house was at the centre of a circular enclosure approximately 30 meters across. The house was 10 meters in diameter, with two doorways, facing east and west. There is an inner ring of 12 post holes approximately 1.5 meters in from the wall. Information courtesy of David Freeman.
