Located in the Llanthony Valley, within Bannau Brycheiniog (Brecon Beacons National Park), this house is a rare survival thought to date from the late 15th century.
Llwyn Celyn is a Grade I listed medieval hall house that's considered one of the most remarkable surviving late medieval houses in Wales.
Largely unchanged for centuries, Llwyn Celyn provides a rare record of how homes developed between the 15th and 18th centuries. Its historic features and remarkably complete layout make it an important example of Welsh and British domestic architecture.
In 2010, we awarded £335,000, matched by Cadw, to help the Landmark Trust acquire Llwyn Celyn, its farmstead and surrounding land. This support enabled the charity to secure the site, begin plans for its restoration and safeguard an important part of the UK’s heritage that was at risk of being lost.
The building was in severe disrepair. Parts of the site had been supported by emergency scaffolding for many years, and there were concerns about its long-term survival. Acquisition was an essential first step towards restoring the site and giving it a sustainable future.
Today, people from across the UK can experience Llwyn Celyn through Landmark Trust holidays in the restored house. Visitors can also explore parts of the wider site, including community and interpretation spaces, helping more people connect with the history of rural Wales and one of the country's most significant medieval buildings.
