The Offa’s Dyke Centre

Positioned precisely at the midpoint of the spectacular 177-mile (285km) National Trail, The Offa’s Dyke Centre in Knighton is the spiritual home of the Anglo-Welsh borderlands. Opened in 1999 and run by the volunteer led Offa's Dyke Association (a charity founded back in 1969), this purpose built heritage centre acts as the ultimate gateway to understanding Britain’s longest and most imposing ancient monument.  

Whether you are a seasoned long distance trekker embarking on the full trail, a day tripper exploring Powys, or a history enthusiast fascinated by early medieval Britain, the centre provides the perfect context before you step out onto the earthworks yourself.

Unlocking the Secrets of the Frontier

At the heart of the centre is a professionally curated, interpretive exhibition that brings the 8th century to life. The displays expertly break down the epic scale of the monument, which was constructed under the orders of King Offa of Mercia to delineate his western boundary against the Welsh kingdoms.
