The Palace Ballroom is now used to host guests and state dinners.
The space is very similar to the Throne room, featuring red carpets, gold panelling, chandeliers and landscape paintings.
The 1844 Room is one of 19 State rooms and is currently used to host world leaders and important guests.
The space features regal decor, including gold mirrors, gold chairs and a pink floral carpet.
The Duke and Duchess of Cambridge met Barack and Michelle Obama in this room a few years ago.
