To the north-west of the castle are earthworks marking the spot of the "Pleasance", created in 1414 by Henry V.[49] The Pleasance was a banqueting house built in the style of a miniature castle.[49] Surrounded by two diamond-shaped moats with its own dock, the Pleasance was positioned on the far side of the Great Mere and had to be reached by boat.[49] It resembled Richard II's retreat at Sheen from the 1380s, and was later copied by his younger brother, Duke Humphrey of Gloucester, at Greenwich in the 1430s, as well by his son, John of Lancaster at Fulbrook.[50] The Pleasance was eventually dismantled by Henry VIII and partially moved into the left-hand court inside the castle itself, possibly to add to the anachronistic appearance.[3] These elements were finally destroyed in the 1650s.[51]
