City Hall, the headquarters of the Greater London Authority, is open to the public on set weekends throughout the year. Visitors have the opportunity to see and walk around some areas that are not normally open to the public during the week. This includes the Chamber, a purpose-built space for meetings and debates; London's Living Room, an open space on the top floor with a walkway around the perimeter offering panoramic views; and the spiral ramp/stairs, which winds its way through the building, offering glimpses of the open-plan offices and the Mayor's Conference Room and views of the Thames and the Tower of London.
