Many of the palace's contents are part of the Royal Collection, held in trust by Elizabeth II; they can, on occasion, be viewed by the public at the Queen's Gallery, near the Royal Mews. The purpose-built gallery opened in 1962 and displays a changing selection of items from the collection. It occupies the site of the chapel that was destroyed in the Second World War. The palace was designated a Grade I listed building in 1970. Its state rooms have been open to the public during August and September and on some dates throughout the year since 1993. The money raised in entry fees was originally put towards the rebuilding of Windsor Castle after the 1992 fire devastated many of its state rooms. In the year to 31 March 2017, 580,000 people visited the palace, and 154,000 visited the gallery.
