The primary royal residence in London is Buckingham Palace. Located in the City of Westminster, Buckingham Palace has served as the official residence and administrative headquarters of the British monarch since the accession of Queen Victoria in 1837. It is also a significant venue for state occasions and royal hospitality. However, there are other royal residences in London as well, such as St. James's Palace, Clarence House, and Kensington Palace, which is the official residence of the Duke and Duchess of Cambridge (Prince William and Catherine) and their family.
