Parish Pages - Crickadarn / Crucadarn - Maps
The map below shows the parish of Crickadarn and its boundaries (in red). The county boundary between Radnorshire (to the northeast) and Breconshire (to the west) is shown in yellow, following the course of the river Wye. The map is based on an Ordnance Survey map from the 1940s, and adapted from the version produced by Kain and Oliver for their work "Historic Parishes of England & Wales":
