Laokoon-Gruppe
Special arrangements were made to allow the public to see many royal or private collections placed in galleries, as with most of the paintings of the Orleans Collection, which were housed in a wing of the Palais-Royal in Paris and could be visited for most of the 18th century. In Italy, the art tourism of the Grand Tour became a major industry from the 18th century onwards, and cities made efforts to make their key works accessible. The Capitoline Museums began in 1471 with a donation of classical sculpture to the city of Rome by the Papacy, while the Vatican Museums, whose collections are still owned by the Pope, trace their foundation to 1506, when the recently discovered "Laocoön and His Sons" was put on public display. A series of museums on different subjects were opened over subsequent centuries, and many of the buildings of the Vatican were purpose-built as galleries. An early royal treasury opened to the public was the Green Vault of the Kingdom of Saxony in the 1720s.
