The office of the Surveyor of the King's/Queen's Pictures, in the Royal Collection Department of the Royal Household of the Sovereign of the United Kingdom, is responsible for the care and maintenance of the royal collection of pictures owned by the Sovereign in an official capacity – as distinct from those owned privately and displayed at Sandringham House and Balmoral Castle and elsewhere. The office has only been full-time since 1972. It now operates in a professional capacity with a staff of a dozen people.
