Buckingham Palace is the official London residence of the British monarch. The palace is a setting for state occasions and royal entertaining, and a major tourist attraction. It has been a rallying point for the British people at times of national rejoicing and crisis.Originally known as Buckingham 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 George III in 1761 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 last major structural additions were made in the late 19th and early 20th century, including the present-day public face of Buckingham Palace. The building is occasionally still referred to as "Buck House".
