Trecastle Motte

Trecastle Motte stands in the village of Trecastell in Powys, a medieval mound built between 1000 and 1153. The site is one of many motte-and-bailey castles across the Welsh Marches, a region stretching through Shropshire, Cheshire, Herefordshire, Powys and Flintshire. It was constructed as a defensive earthwork during a time of frequent border conflicts. The mound was later recognised for its historical importance and registered by Cadw, the Welsh historic environment service, under the reference SAM BR026. This designation helps protect the site for future study and public access. Such mottes are the most common type of castle remains in Britain, with large clusters found in the Marches. Visitors find a grassy mound rising above the surrounding fields, offering a quiet spot to view the landscape. The earthworks show the original defensive layout, with a flat area once enclosed by a ditch and palisade. The site sits near the Afon Chwefri, adding to the rural setting. It provides a tangible link to the medieval period and the region’s turbulent history.
