The large ballroom is 27 metres (89 feet) long and 12.8 metres (42 feet) wide with a 12 metre (40 feet) high ceiling.
This room contains three of the finest Georgian chandeliers in Europe. Made in Staffordshire in1820, each chandelier is 8.5 metres (28 foot) long, contains 20,000 pieces of cut glass crystal and weighs over one ton.
The room has a sprung maple dance floor specially made for dancing. At each end of the room are two massive mirrors specially designed so that people could admire themselves during balls and banquets. Standing in between these two mirrors it is possible to see one's image reflected into infinity.
During major official functions the civic regalia is displayed. This comprises three maces, the Sword of State, the Silver Oar and the Staves.
The staves are symbols of the coach levers, which were once carried by running footmen to prise the wheels of the mayor's coach out of ruts in the road.
Part of the collection was stolen by Charles John Coney in 1784 and although he was convicted of theft and hanged, only part of the regalia was recovered.
