Built by King Henry VIII on the site of a leper hospital dedicated to Saint James the Less, the palace was secondary in importance to the Palace of Whitehall for most Tudor and Stuart monarchs. The palace increased in importance during the reigns of the early Georgian monarchy, but was displaced by Buckingham Palace in the late-18th and early-19th centuries. After decades of being used increasingly for only formal occasions, the move was formalised by Queen Victoria in 1837. Today the palace houses a number of official offices, societies and collections and all ambassadors and high commissioners to the United Kingdom are still accredited to the Court of St James's.
