Originally one of three identical pavilions designed by John Nash for Buckingham Palace and completed in 1831, the conservatory had actually been converted into a private chapel during Queen Victoria’s reign when it was destroyed by air raids in 1940. In 1962 at the request of Queen Elizabeth II and the Duke of Edinburgh the ruins were redeveloped in to a gallery to house the Royal Collection. The Gallery went under a $20million expansion and modernization phase, the most significant addition to Buckingham Palace in 150 years, with the newly renovated Gallery unveiled in 2002 as part of the Queens Golden Jubilee celebrations. The architects appointed for the project were John Simpson & Partners whom successfully created three-and-a-half times more display space than the Gallery previously held. The architecture of the Queens Gallery contains friezes symbolising the reign of Queen Elizabeth II and four panels of each of the Patron Saints of the United Kingdom by Alexander Stoddart. The pieces in the gallery are a unique record of the personal tastes of the Royals over the last 500 years. Much of the monarchies possessions prior to this were destroyed following the execution of Charles I. The Gallery is open daily for the public to enjoy.
