The London Charterhouse is a historic complex of buildings in Smithfield, London, dating back to the 14th century. It occupies land to the north of Charterhouse Square, and lies within the London Borough of Islington. Originally constructed as a Carthusian priory, on the site of a burial ground, at the Dissolution of the Monasteries it became one of the greatest palaces 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 today, although the school was re-established as Charterhouse School in Godalming, Surrey in 1872.
