Buckingham Palace is the official London residence of the British monarch.
The palace is a setting for state occasions and royal entertaining.
 It has been a rallying point for the British people at times of national rejoicing and crisis.
Originally known as Buckingham House (and often colloquially referred to as "Buck House"),
 the building forming the core of today's palace was a large townhouse
 built for the Duke of Buckingham in 1703 and acquired by King George III
 in 1762 as a private residence, known as "The Queen's House". 
It was enlarged over the next 75 years, principally by architects 
John Nash and Edward Blore, forming three wings around a central courtyard. 
Buckingham Palace finally became the official royal palace of the British
 monarch on the accession of Queen Victoria in 1837



The Palace of Westminster, also known as the Houses of Parliament or Westminster Palace, 
in London is where the two Houses of the Parliament of the United Kingdom 
(the House of Lords and the House of Commons) meet to conduct their business. 
The Palace lies on the north bank of the River 
Thames in the London borough of the City of Westminster, 
close by other government buildings in Whitehall.
The palace is one of the largest Parliaments in the world. 
The layout of the Palace is intricate, with its existing buildings containing nearly 1,200 rooms,
 100 staircases and well over three kilometres (two miles) of corridors. 
Although mainly dating from the 19th century, among the original historic buildings is Westminster Hall, 
used nowadays for major public ceremonial events such as lyings in state, and the Jewel Tower.
