Hinchingbrooke House in Huntingdon, Cambridgeshire, was built around an 11th-century nunnery. After the Reformation it passed into the hands of the Cromwell family, and subsequently, became the home of the Earls of Sandwich, including John Montagu, 4th Earl of Sandwich, reputedly the "inventor" of the modern sandwich. The house has also been subject to many 'ghost hunts' due to numerous sightings of paranormal activity, including a nun which apparently haunts the building.
