This 90-foot-long room was added in 17th century and was known as the Long Gallery. The impressive, coffered ceiling, inspired by one in a Roman palazzo was added much later, in the 19th century.
Among the room's outstanding features are:
- A huge, Carrara marble fireplace, copied from the Doge's Palace in Venice
- 17th century Flemish tapestries
- Flamboyant 17th and 18th century furnishings
- 18th century Venetian chairs upholstered with needlworked backs embroidered by the 5th Marchioness of Bath and her daughters in 1926.
