Huberts Folly
Hubert’s Folly is the unfinished earthwork remains of one of the most ambitious castle projects ever attempted in mid-Wales, and one of the most revealing failures of the Anglo-Norman conquest. The site lies on the summit of a prominent hill above Old Hall Farm, near Kerry, commanding wide views across the Severn basin and the uplands of central Powys. The surviving remains consist of a substantial oval enclosure, approximately 50 metres by 41 metres, cut directly into the hilltop. A deep, rock-cut ditch encircles the site, with the upcast material thrown inward to form a strong surrounding rampart. The earthworks are deliberate, heavy, and carefully planned, clearly intended to support a major stone castle rather than a temporary timber fortification. No towers or walls were ever completed, but the scale of the groundworks shows that this was conceived as a flagship fortress. The castle was begun in August 1228 by Hubert de Burgh, Justiciar of England and one of the most powerful men in the kingdom, after he was granted the lordship of Montgomery by King Henry III. Hubert’s intention was to drive deep into Welsh territory and establish a dominant new stronghold to break the power of Llywelyn ap Gruffudd’s father, Llywelyn the Great. The site was chosen for its commanding position and its symbolic assertion of royal authority. The project collapsed almost immediately. Llywelyn responded with speed and force, isolating Hubert’s army and cutting off supplies. What followed was a humiliating military stalemate in the Vale of Kerry. Hubert, outmanoeuvred and politically exposed, was forced to negotiate. As part of the settlement, he agreed to abandon the castle entirely and to dismantle what had already been built. The site was never resumed. The nickname “Hubert’s Folly” reflects both the scale of Hubert’s ambition and the suddenness of his failure. The Latin form Stultitia Huberti appears in later commentary, emphasising how damaging the episode was to his reputation. Within a few years, Hubert de Burgh fell from power entirely, and the unfinished castle became a lasting monument to that downfall. Today, the site survives purely as earthworks. There are no standing stone ruins, as masonry construction never progressed beyond the preparatory phase. The banks and ditch remain clearly legible on the ground, and the hilltop enclosure still conveys the sense of a grand project arrested mid-stride. As a scheduled monument, Hubert’s Folly is preserved not as a triumph of medieval castle building, but as one of its most instructive failures. Alternate names: Hubert’s Folly, Stultitia Huberti, Old Hall Camp, Pen-y-Castell
