Dolforwyn Castle

Dolforwyn Castle stands on a wooded ridge above the village of Abermule in Powys. Built in the late 13th century by Llywelyn ap Gruffudd, Prince of Gwynedd, it commands sweeping views of the upper Severn Valley. The fortification was constructed to assert Welsh authority in a strategic area after Llywelyn’s conquest of Cedewain and Ceri. Its design reflects native Welsh methods rather than the Cambro-Norman style. The castle occupied a rectangular platform carved from rock, measuring about 240 feet by 90 feet. A rectangular keep and a circular tower formed its original core, later connected by ramparts.

The castle’s brief but significant history ended in 1277 when English forces under Roger Mortimer and Henry de Lacy besieged it. Lacking a well, the defenders surrendered when water ran out. The siege may have influenced Edward I’s decision to appoint Master James of Saint George, the architect behind major castles like Caernarfon and Harlech. After its capture, the English modified the site, blocking the south gate and adding new buildings. An inventory from 1322 lists rooms including an armoury, chapel, hall, and storage spaces.

Today, visitors walk among the ruins of the keep, tower, and curtain walls. Excavations between 1981 and 2002 uncovered a cistern, stone-lined hall, and evidence of the 1277 siege. Finds such as a silver coin from Edward II’s reign and stone catapult balls remain on display. The site is managed by Cadw, which has stabilised the masonry to preserve its remains. The name recalls a legend in which Princess Habren drowned in the Severn, linking the castle to local folklore.
