Glas Hirfryn

Glas Hirfryn is a farm in Cwmdu, at east side of the road through the valley of the Lleiriog on the southern side of the Berwyn Mountains. It is in the community of Llansilin, which was formerly in Denbighshire, but since 1996 has been in the Montgomeryshire part of Powys. The timber-framed farmhouse, which stands within a group of farm buildings was abandoned in the mid-20th century, at which time it was listed as Grade II. The house has now been dated by dendrochronology to about 1559 AD or shortly afterwards. By 2002 the building had largely collapsed, but since 2012 a restoration programme has been started under the supervision of architect Graham Moss and drawing on the expertise of the Clwyd-Powys Archaeological Trust (CPAT). The restoration work has been undertaken by Manor Joinery of Minsterley, Shropshire.
