Warkworth Castle is one of the most striking fortresses in north-east England, a large and largely intact Percy family stronghold set on a loop of the River Coquet. English Heritage manages the site. The massive keep, built in the late 14th century on a unique cross-shaped plan, dominates the village from its hill and is the most recognisable part of the complex.
Inside the outer walls you can walk through the great hall, the kitchen, and the chapel. The keep's cross-shaped floor plan — rare in English castle design — allowed light and ventilation into every room and gave the Percy lords something closer to palatial accommodation than a spartan fortress. The views from the top extend over the village, the river, and the dunes along the coast.
The castle is open to visitors year-round except in winter (October–March, when opening hours are reduced). Audio guides are available. Entry is charged; English Heritage members enter free.
