The exterior of the Earl-Bishop’s Rotunda was virtually finished when he died in 1803, but the interior was still an empty shell, and the curving corridors and wings only a few feet above ground. It was left to the Earl-Bishop’s son, the future 1st Marquess of Bristol, to make what use he could of his father’s extraordinary plan. Having no need for massive galleries, in 1821 he instructed his architect, John Field, to redesign the East Wing as family living-quarters.

Field fitted out the ground floor of the Rotunda as state rooms in an austere Regency style. The West Wing was added purely for symmetry and so was left empty. The Trust is pleased to announce the go-ahead of a package for a project to develop the West Wing to provide new facilities for visitor reception, information, education, shop, restaurant, functions, conferences and events.

As the family lived mostly in the East Wing, the rooms that visitors see in the Rotunda spent much of the year under dust sheets, coming into their own mainly for parties and other special occasions. But as a result, their superb furnishings and decoration have survived in excellent condition and little changed since the heyday of the house in the Edwardian era.

The house, with much of its collections of family portraits, Huguenot silver, Regency furniture and china, and part of the ancient deer-park, passed to the National Trust in 1956.
