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. The Charterhouse began as (and takes its name from) a Carthusian priory, founded in 1371 and dissolved in 1537. Substantial fragments remain from this monastic period, but the site was largely rebuilt after 1545 as a large courtyard house. More information on the Wikipedia page [1]
