Palace of Westminster

About

The Palace of Westminster is the meeting place of the Parliament of the United Kingdom and is located in London, England. It is colloquially known as the Houses of Parliament after the House of Commons and the House of Lords, the two legislative chambers which occupy the building. The palace is one of the centres of political life in the United Kingdom; "Westminster" has become a metonym for the UK Parliament and government, and the Westminster system of government commemorates the name of the palace. The Elizabeth Tower of the palace houses the bell nicknamed Big Ben and is a landmark of London and the United Kingdom in general. The palace has been a Grade I listed building since 1970 and part of a UNESCO World Heritage Site since 1987.

The building was originally constructed in the eleventh century as a royal palace and was the primary residence of the kings of England until 1512, when a fire destroyed the royal apartments. The monarch moved to the adjacent Palace of Whitehall, but the remainder of the palace continued to serve as the home of the Parliament of England, which had met there since the 13th century. In 1834 a second, larger fire destroyed the majority of the palace, but the eleventh century Westminster Hall was saved and incorporated into the replacement building.
