Ickworth House is a country house near Bury St. Edmunds, Suffolk, England. It is a neoclassical building set in parkland. The house was the residence of the Marquess of Bristol before being sold to the National Trust in the late 20th century.
The house built between 1795 and 1829, was formerly the chief dwelling of an estate owned by the Hervey family, later Marquesses of Bristol, since 1467.
As one of England's more unusual houses, Ickworth has been unflatteringly described as resembling "a huge bulk, newly arrived from another planet" and as "an overgrown folly" Yet, is now being architecturally re-asessed and recognised as the only building in England comparable with the monumental works of Boullée and Ledoux.
Paintings by Velázquez, Titian, Poussin, and Claude Lorrain, as well as an unrivalled series of 18th-century family portraits by artists such as Gainsborough, Reynolds, Vigee-Lebrun, Batoni, Angelica Kauffman, Ramsay, Van Loo, and Hogarth. In addition, Ickworth has arguably the best collections in Britain of fine Georgian silver.
