The Offa's Dyke Centre is positioned at about the halfway point of the Offa's Dyke Path National Trail and at the start of the Glyndŵr's Way National Trail. It is managed by the Offa's Dyke Association and incorporates the Knighton Tourist Information Centre and a shop.
The Centre, opened in 1999, forms the focus for activities based on the 8th Century earthwork built by Offa, the King of Mercia. The dyke follows the Welsh English border from the hills above Prestatyn to the Severn Estuary near Chepstow. With its free exhibition and car park, the Centre caters for the needs of a wide range of visitors, from those taking toddlers to play in the surrounding park and play area, to those exploring the border area by car, cycle or on foot, to education groups studying the history of the area, and particularly that of Offa's Dyke.
