Clun Castle is a ruined castle in the small town of Clun, Shropshire . It is owned by the Duke of Norfolk (who also holds the title of Baron Clun) and is managed by English Heritage.
The castle was originally established by Picot de Say, a Norman baron, around 1100 as a substantial motte castle with two baileys. The area surrounding the castle was a border barony, known as the Honour of Clun, which meant it was governed by its own laws. In 1196 the castle was besieged by the Welsh and it then came into the ownership of the FitzAlan family, who also established the surrounding town. They rebuilt the castle which became an important administrative building. The family abandoned the castle in the 1270s to concentrate their efforts on their more impressive castle, Arundel Castle. After their departure the castle started to fall into ruin. By the 16th century it had fallen into disuse, and the castle passed to the crown.
In 1894, the site was purchased by the Duke of Norfolk, a descendant of the original FitzAlan family. The remains of the 80-foot tall keep are still standing on the site today together with remnants of the curtain wall.
