Upton House was built at the end of the 17th century but was remodelled in the 1920s. The house is chiefly renowned for its paintings and for its china collection. The paintings include works by El Greco, Bruegel, Bosch, Hogarth, Stubbs, Memling and Guardi. The china collection includes Chelsea figures and superb examples of beautifully decorated Sevres porcelain. There is also a set of 17th century Brussels tapestries.
The outstanding gardens, which are of interest throughout the year, have a series of terraces descending from the main lawn into a deep valley. There are herbaceous borders, the national collection of asters, over an acre of kitchen garden, a water garden and pools stocked with ornamental fish.
