Lydiard House is a manor house located in Lydiard Park at Lydiard Tregoze, Swindon, Wiltshire. The house and surrounding land was originally owned by the Viscount Bolingbroke. The family owned the house for several centuries until the cost of caring for the house proved too high, and they were forced to sell. The house is now owned by Swindon Borough Council who remodelled it and opened it up as a museum for the public.
