Built in 1273 by Llywelyn ap Gruffydd (Llywelyn the Last), a Welsh Lord, Dolforwyn Castle stands on a prominent hillside overlooking the Severn valley. After lord Roger Mortimer defeated Dolforwyn in 1277 after a two-week battle, the castle was eventually abandoned in the 14th century. Recent excavations have unearthed its atmospheric remains.

Clun Castle is a Grade I-listed Norman fortress dating back to the 11th century. A vital line of defence in case of an attack from the Welsh, the castle then lost its importance to Arundel Castle. This historic building was ruined by the 16th century and today is managed by English Heritage and owned by the Duke of Norfolk. Despite its ruined state, it remains very impressive and is free to enter.

he dramatic riverside ruins and extensive earthworks of this Welsh border castle sit high on a rocky mound on the edge of the small, picturesque town of the same name. Unusually, the castle's tall 13th century keep is set on the side of its mound. Founded shortly after the Norman Conquest, the castle and nearby settlement prospered until the early 15th century, when followers of the Welsh chieftain Owain Glyn Dwr devastated the surrounding area. Every year the Castle is host to two community events; the Green Man Festival on the first weekend in May and the Clun Carnival and Show during August. Please note the Green Man Festival has been cancelled for 2020 and will return in 2021.
