The Bath Assembly Rooms, designed by John Wood the Younger in 1769, are a set of assembly rooms located in the heart of the World Heritage City of Bath in England which are now open to the public as a visitor attraction. They are designated as a Grade I listed building. The building, made of Bath stone, is arranged in a U shape. There are four main function rooms in the complex: the 100-foot-long (30 m) ballroom — the largest Georgian interior in Bath; the tea room; the card room; and the octagon. The rooms have Whitefriars crystal chandeliers and are decorated with fine art.
