This remaining piece was part of the Great Cloister, which was part of the Carthusian monastery that was founded outside the city of London by Sir Walter Manny. Manny also funded the plague burial site which is now Charterhouse Square. The Norfolk Cloister is a 'rare survival of a great Elizabethan garden gallery'. The roof was used for guests to promenade including by Queen Elizabeth I during her visit to the Charterhouse.
During the period of Sutton's Hospital the cloister was used by the schoolboys for football, its narrow dimensions leading to the invention of the offside rule.
Date: 1417 (the Great Cloister) & 1571 (roof and inner wall)
