There are many other heritage sites open to visitors in the National Park. Some of these are based on important houses and their collections of artworks and furniture such as Petworth House or Arundel Castle, others are more modest houses that give an insight into ways in which people used to live, these include Glynde Place and Uppark. Great estates (and more modest houses) were also the centre of great planned landscapes and gardens. The National Trust has a number of ‘country house’ holdings in the National Park with important designed landscapes, some of which still survive such as Petworth House designed by Capability Brown and Hinton Ampner designed by Ralph Dutton.
There are also heritage sites that are associated with famous writers, poets, natural historians, composers or artists. For example Jane Austen House, Chawton; Gilbert White House and Oates Museum, Selborne and Charleston farmhouse, Firle.
Many of the historic houses are also major venues for a wide range of activities from opera at Glyndebourne to horseracing and motor events at Goodwood – where the needs of the historic environment need to be balanced with economic and cultural activities and the potential encouragement of sustainable tourism (see Chapter 5 for more detail).
