The Palace of Westminster occupies a site of approximately 3.24 hectares (8 acres) on the west bank of the Thames, it has approximately 1,000 rooms, 100 staircases, and two miles of passageways. The 320ft high slim Clock Tower is undoubtedly the most famous feature, and houses the bell known as Big Ben, from which the Clock Tower is colloquially, but inaccurately named.
