NOTES: Founded in 1120 around a Norman gate tower, this castle was significantly enlarged in the 13th century. It was lavishly turned into a palace fortress designed in Perpendicular style by John of Gaunt in the late 14th century while Tudor additions were made by the Earl of Leicester in the 1570s.
