The Palace of Westminster serves as the meeting place for both the House of Commons and the House of Lords, the two houses of the Parliament of the United Kingdom. Informally known as the Houses of Parliament after its occupants, the Palace lies on the north bank of the River Thames in the City of Westminster, in central London, England.
Its name, which derives from the neighbouring Westminster Abbey, may refer to several historic structures but most often: the Old Palace, a medieval building-complex largely destroyed by fire in 1834, or its replacement, the New Palace that stands today. The palace is owned by the monarch in right of the Crown and, for ceremonial purposes, retains its original status as a royal residence. Committees appointed by both houses manage the building and report to the Speaker of the House of Commons and to the Lord Speaker.
The first royal palace constructed on the site dated from the 11th century, and Westminster became the primary residence of the Kings of England until fire destroyed the royal apartments in 1512.
