On the east side of the Platz der Demokratie in Weimar stands the Grünes Schloss (Green Castle), a Renaissance building of 1563 which was rebuilt in simplified form in the 18th C, with a magnificent library hall. It is now occupied by the Central Library of the German Classical Period (Zentralbibliothek der deutschen Klassik).
On the south side of the Platz der Demokratie in Weimar is the Fürstenhaus (1774), a three-story Baroque building with a colonnade added in 1889. It is now occupied by the Academy of Music (Hochschule für Musik). In front of the building is an equestrian statue of Grand Duke Carl August (by A. von Donndorf, 1875).
On the west side of the Platz der Demokratie in Weimar is the Rotes Schloss (Red Castle; 1574-76), with a Renaissance doorway. Nearby is the Gelbes Schloss (Yellow Castle), a two-story Baroque building begun in 1702. In the courtyard is an amusing figure (by G. Elster) of the "Aktenmännchen" (civil servant).
