Harewood Castle is a grade I listed 14th-century stone fortification built in 1366 by Sir William de Aldeburgh on the Harewood Estate in West Yorkshire. The castle's distinctive architecture features a keep with a rectangular layout and four corner towers, with the main hall rising two storeys and a three-storey accommodation wing adjoining a chapel situated over the portcullis chamber. Though it served as a romantic ruinous landmark through the 18th and 19th centuries—painted multiple times by the celebrated artist J.M.W. Turner—the castle faced deterioration until placed on the English Heritage Buildings at Risk Register. Following substantial restoration efforts completed in 2008, the castle's ruins are now accessible to visitors at no charge, offering insight into medieval military architecture and baronial life.
