Prudhoe Castle is a Norman castle which was for a long time involved in the border wars between England and Scotland. It was built by the de Umfraville family - the Norman Sir Robert de Umfraville was granted the freedom of Redesdale by William the Conqueror. For much of its history the castle was owned by the Percy family. It is now run by English Heritage.
The majority of the surviving building work dates from the 12th century, although the site of Prudhoe Castle has strong Norman origins. In the 14/15th century the tower was extended to provide an extra level with turrets. Only the southwest turret survives to this day.
