In 2007, two new replica Iron Age round houses were built next to the 18th Century Melin Llynnon on Anglesey. A company from Deganwy called Ancient Arts, specialising in experimental archaeology, were commissioned to build the round houses. The houses were built using a Forestry Commission Wales Cydcoed grant, with the aim of using completely natural materials. These natural materials includes trees that have been planted on site to provide materials to refurbish the buildings in years to come.
