Gatehouse and range at the St Pierre Hotel - Credit: Wikimedia Commons
The Gatehouse and attached range, at the St Pierre Hotel, St Pierre, Mathern, Monmouthshire are the most significant remains of the mansion built by the Lewis family in the late 15th century and owned by them until 1924. The original house was built by William Lewis, and extended by his son George, between 1475 and 1508. After the Lewises sold up, the house had a variety of owners and was converted to the clubhouse of a golf club in 1962. It has since been massively extended as a hotel and country club. The gatehouse and range have Grade II* listed building status. The surrounding gardens are included on the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales.
