Hinchingbrooke House, on the western outskirts of Huntingdon, is a remarkable survival — a medieval nunnery converted into a country house in the 16th century, then expanded over several centuries into a complex and attractive building that mixes Tudor, Jacobean, and later additions with visible medieval remnants. The house is now part of Hinchingbrooke School, which has preserved and cared for it over the past half century.
The house is open to visitors on occasional days arranged by the school; check the Hinchingbrooke House website for current open days. The grounds, which include formal gardens and parkland, can sometimes be accessed independently. The house's long connection to the Cromwell and later Sandwich families makes it an interesting secondary stop for anyone who has visited the Cromwell Museum in town.
