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.
