The London Charterhouse is a historic complex of buildings in Farringdon, London, dating back to the 14th century. It occupies land to the north of Charterhouse Square, and lies within the London Borough of Islington. It was originally built a Carthusian priory, founded in 1371 on the site of a Black Death burial ground. Following the priory's dissolution in 1537, it was rebuilt from 1545 onwards to become one of the great courtyard houses of Tudor London. In 1611, the property was bought by Thomas Sutton, a businessman and "the wealthiest commoner in England", who established a school for the young and an almshouse for the old. The almshouse remains in occupation today, while the school was re-located in 1872 to Godalming, Surrey.
