Dresden houses some of the greatest art treasures in the world. For centuries, Saxon electors collected art from around the globe and brought them to Dresden. Many of the pieces survived World War 2 bombings. Today, the public can view delicate Oriental porcelain, sensitive paintings by great artists, and treasures in the Green Vault made of precious metals and jewels by European artisans such as diamond boot buckles and jeweled shirt buttons. The value of these treasures is virtually impossible to estimate as many are priceless.
