The core of the medieval castle is a 14th-century solar tower surrounded by a Tudor house. It was extended in Elizabethan times and has oak-panelled interiors, including the Inlaid Chamber, complete with period furniture and panelling inlaid with poplar and oak. The contents of the Inlaid Chamber had been sold to the Victoria and Albert Museum (V&A). During the last part of the 20th century, the V&A starting loaning the panelling back piecemeal. The entirety of the panelling was restored in 1999 under a long-term loan. Around 1770, the great hall was again expanded in the Georgian style.
