Another Georgian building designed by John Wood the Younger is the Assembly Rooms. This venue for balls, concerts and other high society events opened in 1771. The 100 foot Ball Room is the largest of its four halls. At the end of the 18th century, it accommodated up to 1,200 dancing quests twice a week. The others rooms are the Great Octagon, Tea Room and Card Room. Also inside is the Fashion Museum. This historic property is now owned by the National Trust and managed by the local council.
