The Palace of Westminster, the medieval royal palace used as the home of the British parliament, was largely destroyed by fire on 16 October 1834. The blaze was caused by the burning of small wooden tally sticks which had been used as part of the accounting procedures of the Exchequer until 1826. The sticks were disposed of carelessly in the two furnaces under the House of Lords, which caused a chimney fire in the two flues that ran under the floor of the Lords' chamber and up through the walls.

The Palace of Westminster is the meeting place of the Parliament of the United Kingdom and is located in London, England. It is commonly called 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 the centre of political life in the United Kingdom; "Westminster" has become a metonym for the UK Parliament and the British Government, and the Westminster system of government commemorates the name of the palace. The clock bell in the Elizabeth Tower of the palace, nicknamed Big Ben, is a landmark of London and the United Kingdom in general. The Palace of Westminster has been a Grade I listed building since 1970 and part of a UNESCO World Heritage Site since 1987.
