Der Zwinger in Dresden, Sachsen, Eastern Germany
Der Dresdner Zwinger is a palace built in Baroque style, designed by court architect Matthäus Daniel Pöppelmann. It served as orangery, exhibition gallery, and festival arena of the Dresden Court. The location was formerly part of a fortress of which the outer wall is conserved. The name derives from the German word Zwinger (an enclosed killing ground in front of a castle or city gate); it was for the cannons that were placed between the outer wall and the main wall. The Zwinger was not enclosed until the Neoclassical building by Gottfried Semper called the Semper Gallery was built on its northern side.
Today, it is a museum that contains the Gemäldegalerie Alte Meister (Old Masters Picture Gallery), the Dresden Porcelain Collection (Dresdener Porzellansammlung) and the Mathematisch-Physikalischer Salon (Royal Cabinet of Mathematical and Physical Instruments).
