The Dresden Zwinger ranks among the most impressive buildings of the baroque. Its construction was commissioned and supervised by Augustus the Strong (1670-1733), Elector of Saxony and King of Poland. Apart from many others, architect Matthaeus Daniel Poeppelmann (1662-1736) and sculptor Balthasar Permoser (1651-1732) were the two extraordinarily virtuous artists who contributed to the uniqueness of the Dresden Zwinger. Poeppelmann’s famous copper engraving works on the Zwinger have been preserved until our days.Two round (the Wall Pavilion and the Glockenspiel Pavilion) and four rectangular pavilions symmetrically frame the rectangular inner yard, decorated with lawns and fountain basins. The pavilions are connected among each other by arched galleries and the Long Gallery. The latter rests on what used to be fortification walls and is interrupted by the Crown Gate. The Semper Wing closes the area off to the north. In 1709, senior state master builder Matthaeus Daniel Poeppelmann was commissioned with erecting an orangery in the Zwinger garden to accommodate orange trees and other potted plants in winter.
