Castell Dolforwyn is a late thirteenth-century Welsh castle built on a hilltop near Newtown in Montgomeryshire. Constructed by Llywelyn ap Gruffydd, Prince of Gwynedd, the castle served as a stronghold to defend Welsh territorial interests against English expansion during the final decades of independent Welsh rule. The site comprises a stone keep and defensive walls positioned strategically on elevated terrain, demonstrating characteristic features of high medieval military architecture adapted to the Welsh borderlands. Following the conquest of Wales by Edward I, the castle was slighted in 1277, effectively ending its military function, though substantial remains of its stone fortifications survive today.
