The extensive walls and terraces provide a great way to appreciate the Castle's impressive setting with fantastic views over the surrounding countryside and the Capability Brown designed landscape. The impenetrable stone towers around the inner and outer bailey are home to several fascinating museums and exhibitions.
Constable's Tower
During the Napoleonic Wars this country faced a very real threat of invasion. No single act in Percy history demonstrates better the workings of a great landed estate, the interplay of characters and events, and the fusing of national and local concerns, than the raising of the Percy Tenantry Volunteers in 1798.
The stories told in this fascinating exhibition are based on the real-life personal histories of some of those involved and found in the surviving records.
Postern Tower
An important collection of British and Irish archaeology which provide a window into Northumberland's ancient past. This tower has been a museum since 1826.
Under the patronage of the 4th Duke many important archaeological investigations and digs were undertaken and so began the collection. Estate lands today continue as sites for productive investigations and digs, adding to and enhancing the collection.
Abbot's Tower
Home of the Fusiliers Museum of Northumberland. The museum was founded to perpetuate the history of the Royal Northumberland Fusiliers and to show its continuation as part of The Royal Regiment of Fusiliers. It maintains a collection of uniforms, medals, weapons, paintings and memorabilia relating to the various historical campaigns in which the Regiment has fought.
Entry to the museum is included in the admission charge for the Castle. The archives of the Fusiliers Museum of Northumberland accepts research enquiries that are made in writing and for which there is a charge of £20. Limited access to first and second floor displays, wheelchair access ground floor only.
The Coach House
The grand and luxurious state coach which now carries the Percy livery once carried that of royalty when it transported the 3rd Duke as King George IV's personal representative to the coronation of Charles X in France in 1825. Now bearing the arms of the 7th Duke and Duchess, re-painted in 1902 for their use at the coronation of King Edward VII, it can be seen on display in the Coach House in the Castle courtyard, alongside a collection of vehicles from the 19th century.
