The building that originally stood on the site of the current Queen’s Gallery was designed by John Nash as one of Buckingham Palace’s three identical conservatories or pavilions in the form of Ionic temples. It was constructed on the south-west corner of the Palace, facing the garden, and was completed in 1831. The conservatory was converted into a private chapel for Queen Victoria in 1843, but destroyed in an air raid in 1940. At the suggestion of The Queen and The Duke of Edinburgh, it was redeveloped as a gallery for the Royal Collection in 1962.
