Located on the Welsh border, the market towns of Brecon and Hay-on-Wye have been important settlements since the Norman conquest of 1066 and still retain traces of their Norman past, such as Brecon Priory (now Brecon Cathedral) and Hay Castle (recently restored). Medieval market-places and Georgian-style houses in the town centres of Brecon and Hay are witnesses to their commercial importance over the centuries, with later buildings adding to the varied streetscapes.

Based on historic OS mapping, these new maps bring alive two Norman Marcher towns, fourteen miles apart, and today quite different in size and purpose, but sharing a history of border warfare, ecclesiastical importance, and commercial significance.

Printed in full colour, the maps show the medieval and early modern streetscapes of Brecon and Hay-on-Wye and include a descriptive gazetteer of historic buildings, including those no longer visible. Informative and educational, these town maps are a major contribution to understanding the history of the March of Wales.
