The Green Vault is a museum located in Dresden, Germany, which contains the largest treasure collection in Europe. The museum was founded in 1723 by Augustus the Strong of Poland and Saxony, and it features a variety of exhibits in styles from Baroque to Classicism. The Green Vault is named after the formerly malachite green painted column bases and capitals of the initial rooms. It has some claim to be the oldest museum in the world; it is older than the British Museum, opened in 1759, but the Kunstkamera in St. Petersburg, Russia was opened in 1714 and the Vatican Museums date their foundation to the public display of the newly excavated Laocoön group in 1506.
