Begun between 1100 and 1120 to defend a strategic crossing of the River Tyne against Scottish invaders, Prudhoe Castle has been continuously occupied for over nine centuries. After two sieges during the 1170s - the Scots attackers reportedly declaring 'as long as Prudhoe stands, we shall never have peace' - the mighty stone keep and a great hall were added, followed in about 1300 by two strong towers. Passing from its original Umfraville owners to the powerful Percies in 1398, it was again updated with a fashionable new great hall.
Even after its last military action against the Scots in 1640, Prudhoe's importance as the centre of a great landed estate continued. Early in the 19th century the Percies restored it, building a fine new manor house within its walls. All these developments are now vividly interpreted in a family-friendly exhibition including site finds, helping visitors to explore and understand the extensive remains of this formidable and long-lived fortress.
