Mapping the Historic Boundaries of Wales: Commotes and Cantrefs
Understanding the historic administrative boundaries of Wales and how they have changed over time is integral to our understanding of the Welsh landscape. The Royal Commission has developed two digital geospatial layers using late-medieval sources and historic parish boundaries to recreate the boundaries of the commotes (cymydau) and cantrefs (cantrefi) of medieval Wales.
Future developments will examine how these boundaries have changed over time and map them in further detail. These digital resources will be made freely available to the public as an aid to encouraging research.
