[3] The house is surrounded by a moat 60 feet wide, over which it is reached only by two working drawbridges, which have been pulled up every night since 1510.
[5] In addition to the house and gardens, several other buildings and structures on the estate are listed Grade II.
The garden wall to the south west of the hall,[6] two urns and a male and female statue,[7][8][9][10] a sundial and an obelisk,[11][12] the tea rooms, bridge, game larder, and revetment are all listed Grade II.
[17][18][19][20] The Church of St Mary on the edge of the park has connections with the Tollemache family dating back to the Middle Ages.
[27] The "Tollemache lute manuscript" was acquired from the Helmingham Hall collections and sold by Sotheby's in 1965 to Robert Spencer.
[29] Catherine Tollemache lived at the hall from 1581 to 1612, many household papers from her time survive, with her collection of contemporary and medieval recipes.
