Caergwrle Castle, built between 1278 and 1282 by Dafydd ap Gruffudd, stands as the last castle constructed by a native Welsh prince before English conquest reshaped the medieval Welsh landscape. Granted lands by Edward I, Dafydd used Caergwrle as a base for his 1282 attack on Hawarden, an assault that sparked Edward's decisive second Welsh campaign that ended Welsh independence. The castle likely remained incomplete when abandoned following a fire, becoming ruinous by 1335, yet its earthworks and stone remains survive in the village of Caergwrle in Flintshire. Now protected by Cadw through guardianship, the castle is accessed via a moderate woodland path from the village center, making it an accessible and contemplative site where visitors can reflect on the final chapter of native Welsh rule in medieval Britain.
