Buarth-Mawr Barn is a medieval barn standing in Wales on bedrock of the Lias Group, a sequence of mudstone, siltstone, limestone and sandstone laid down during the Aalenian period of the Jurassic era. The barn is protected as a scheduled ancient monument by Cadw under the reference number GM148, reflecting its significance as a surviving example of medieval rural architecture.
Medieval barns served essential functions within agrarian economies, storing harvested grain and providing shelter for threshing and processing crops. Buarth-Mawr Barn's survival into the present day makes it a valuable record of medieval farming practices and building techniques in Wales. Such structures were typically constructed to maximise internal space whilst withstanding the demands of heavy storage loads and repeated use over generations.
The barn's location on stable Jurassic bedrock would have provided a solid foundation for its substantial timber frame or stone walls. Understanding the building's original plan, materials and any modifications over time contributes to knowledge of how Welsh communities managed agricultural production and storage during the medieval period and beyond.
