Dolforwyn Castle was constructed by Llywelyn ap Gruffydd, Prince of Gwynedd, between 1273 and 1277, in a strategic position overlooking the Severn Valley. This caused tension with the English king, Edward I, whose frontier post was at nearby Montgomery Castle. In 1277 shortly after the castle had been completed Roger Mortimer and Henry de Lacy, Earl of Lincoln successfully besieged the castle. The new English owners made modifications to the castle which remained occupied until the late 14th century.
