the Belvedere. Belvedere in the First and Second Republic Shortly after the end of the war in November 1918, the art historian Franz Haberditzl submitted a request to the Ministry of Education, asking for the palaces to be left to the Staatsgalerie. This application was granted the very next year. The nationalization of the Belvedere palace complex was also laid down in the draft document to reorganize the former imperial collections drawn up by Hans Tietze in 1920–21. In addition to the museums that still exist today, it also included plans to set up an Österreichische Galerie (Austrian Gallery) and a Moderne Galerie. During the 1921–23 reorganization the Baroque Museum in the Lower Belvedere was added to the existing museum ensemble. The Moderne Galerie was opened in the Orangery in 1929. The palaces suffered considerable damage during World War II. Parts of the Marble Hall in the Upper Belvedere and the Hall of Grotesques in the Lower Belvedere were destroyed by bombs. After reconstruction work was completed, the Österreichische Galerie reopened in the upper palace on 4 February 1953. The Baroque Museum opened in the lower palace and the Museum mittelalterlicher österreichischer Kunst ("Museum of Medieval Austrian Art") opened in the Orangery on 5 December 1953. The Lower Belvedere and the Orangery have been specially adapted to stage special exhibitions. After winning an invitation-only competition, architect Susanne Zottl turned the Orangery into a modern exhibition hall whilst still preserving the building's original Baroque fabric. This venue opened in March 2007 with the exhibition Gartenlust: Der Garten in der Kunst (Garden Pleasures: The Garden in Art). A few months later the Lower Belvedere reopened with the show Vienna – Paris. The redesign of the building was carried out by the Berlin architect Wilfried Kuehn, who moved the entrance back to its place in the cour d'honneur, thereby once more freeing up the original line of vision from the main gate of the Lower Belvedere via the Marble Hall to the garden facade of the Upper Belvedere. The various sections of the original orangeries annexed to the Marble Hall were returned to their original condition and now provide space for the new exhibition rooms. The magnificent Baroque state rooms – the Marble Gallery, the Golden Room, and the Hall of Grotesques – remain unchanged and are open to the public.
