Houses of Parliament London, United Kingdom

For over 900 years this impressive assemblage of Gothic buildings has been the home of British government. The building covers an area of eight acres and consists of 1100 rooms, 100 staircases and 11 courtyards. The House of Lords occupies the southern end of the building while the House of Commons occupies the area to the north. The best view of this massive expanse can be seen from nearby Parliament Square. Within the Houses of Parliament there is Westminster Hall, the Crypt Church, Members' Lobbies, the Commons Library and the Peers Library. The tower containing Big Ben looms just outside. To attend PMQ (Prime Minister's Question Time) in the House of Commons, UK citizens need to contact their local MP in advance. Otherwise, there is a queue at St Stephen's entrance. Admission is free.
