1777/1778 the Königskolonnaden, originally near Alexanderplatz but later relocated to Heinrich-von-Kleist-Park); the Oranienburg Gate (1787/88) historic drawing; and supervision of the construction of the Royal Library on today's Bebelplatz, which he furnished with a grand staircase and a formal hall for festivities. Immediately after the death of Frederick the Great, his successor, Friedrich Wilhelm II, commissioned Gontard to decorate the Potsdam City Palace and Garrison Church for the funeral rites. Major royal assignments followed. Between 1787 and 1790 he furnished nine of the Royal Chambers in the Berlin City Palace. At the same time he created the Marble Palace in Potsdam, one of his most outstanding achievements. His last work was the ‘‘Holländische Etablissement’’, an ensemble of so-called “Dutch Houses” in the New Garden, Potsdam. Under Frederick William II Gontard became a member of the Royal Prussian Academy of Arts and Mechanical Sciences, where he taught until his death. He had significant followers in G. C. Unger, F. W. Titel, and H. Gentz, but no long-lasting successors as his style did not survive the change in architectural taste that came with the end of Frederick the Great's era.
