Great Killough

Great Killough is a remarkable manor house located in Llantilio Crossenny, Monmouthshire, with origins dating back to the late medieval period. The current structure, a Grade II* listed building, showcases architectural features from three distinct building phases between 1600 and 1670. Notable for its H-plan design, the house is constructed from Old red sandstone and features a rare four-bay great hall. The site has historical significance, with evidence of a panelled attic that may have served as a chapel. Great Killough remains privately owned, offering a glimpse into the rich architectural heritage of the Welsh countryside.
