Buckingham Palace is synonymous with the kings and queens of England. However, it wasn't built by or for them. John Sheffield, the first Duke of Buckingham, ordered the demolition of an existing house in Westminster and built a new palace on the same site in 1703. It was called Buckingham House and was later purchased by King George III in 1761. When Queen Victoria took over the throne in 1837, she named Buckingham Palace her official residence.
