East Riddlesden Hall is a 17th-century manor house in Keighley, West Yorkshire, England, now owned by the National Trust. The hall was built in 1642 by a wealthy Halifax clothier, James Murgatroyd. The hall is a Grade I listed building. There is a medieval tithebarn in the grounds.
East Riddlesden Hall perches on a small plateau overlooking a bend in the River Aire on its way downstream from the town of Keighley. Interesting features include well-restored living accommodation on two floors, two Yorkshire Rose windows, walled garden, the ruined Starkie wing and several ghosts . A hiding place for Catholic priests was installed during the 16th century.The property was extended and re-built by James Murgatroyd and his wife Hannah, using local Yorkshire stone, in 1648. He also built other stone manor houses throughout the West Riding of Yorkshire. In the great hall, a small fireplace can be seen above the main fireplace, where the floor for the first floor accommodation was not built. James Murgatroyd was a Royalist and this can be seen in royalist symbols and graffiti on and in the building. For example, the Bothy has the heads of Charles I of England and Henrietta Maria of France carved in the topmost stone work.
According to a NODA National News feature in 2007, the Murgatroyd family are reputed to be the inspiration for the Murgatroyd Baronets in the comic opera Ruddigore by Gilbert and Sullivan, and the opera has been performed at the Hall. W. S. Gilbert is supposed to have often stayed at the Hall. The feature comments that the Murgatroyds became notorious "for their profanity and debauchery". A legend arose that the River Aire changed its course in shame, in order to flow further away from the hall and its occupants . The feature continues "Members of the family were fined, imprisoned and excommunicated". It asserts that the character of Sir Despard Murgatroyd in Ruddigore is based on James Murgatroyd.
