There is a nineteenth century garden within the castle but the historically interesting feature is the renaissance King's Knot which can be seen from the ramparts. It was described as new in 1502 and is set apart from the castle. Obviously, it could be used only in peaceful times. The earthworks survive, though they were modified in the nineteenth century and are now unplanted. John Harvey commnets that the parterres 'though repeatedly reformed, do occupy the site of a great garden which was probably laid out by James I soon after 1424, in imitation of the King's Garden below Windsor Castle where he had first seen his queen'.
