Buckingham Palace is the official London residence of the British monarch. Located in the City of Westminster, the palace is a setting for state occasions and royal hospitality, 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 which forms 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 centuries, including the present-day public face of Buckingham Palace. However, the palace chapel was destroyed by a German bomb in World War II; the Queen's Gallery was built on the site and opened to the public in 1962 to exhibit works of art from the Royal Collection.

The original early 19th-century interior designs, many of which still survive, included widespread use of brightly coloured scagliola and blue and pink lapis, on the advice of Sir Charles Long. King Edward VII oversaw a partial redecoration in a Belle epoque cream and gold colour scheme. Many smaller reception rooms are furnished in the Chinese regency style with furniture and fittings brought from the Royal Pavilion at Brighton and from Carlton House. The Buckingham Palace Garden is the largest private garden in London, originally landscaped by Capability Brown, but redesigned by William Townsend Aiton of Kew Gardens and John Nash. The artificial lake was completed in 1828 and is supplied with water from the Serpentine, a river which runs through Hyde Park.
