The Hall was built by Thomas Ripley in the 1720s for Horatio Walpole: politician, diplomat  and younger brother to Britain's first Prime Minister - Sir Robert Walpole.

Other members of the family made alterations in the early 19th century, including adding a wing and enclosing the Park. On the death of the 3rd Earl in 1858 the Hall was abandoned and his son moved to Mannington.

The property was restored when the Earl moved back in 1905.

The present Lord Walpole inherited the property in 1989.  Since, there has been a programme of reorganisation, conservation and research into the history of the family, Hall and Park using extensive and previously neglected archives. There is an extensive family portrait collection.

The Park contains evidence of the village of Wolterton with its round church tower which can still be seen.  The 18th Century walled garden is now let and run by Barker Organics as a smallholding.

A special exhibition for 2011 was Wickmere to Westminster - Walpoles and ‘their’ churches.  Each year a different aspect of the collections not usually on view is displayed; last year the theme was illustrated by watercolours, drawings, prints and photographs as well as archive material and associated artefacts including costumes with bibles and prayer books.

Wolterton Forge is run by artist blacksmith Baron Tremain. It is open by appointment and on special days. See local listings or contact 01263 768003.
