The main building of the German National Library in Leipzig was built 1914–1916 after plans of the architect Oskar Pusch. The impressive facade is 160 m long and faces the "Deutscher Platz". The building was opened on October 19, 1916, one day after the monument for the Battle of the Nations. Emperor Wilhelm II had already left in a huff, as the Leipzig citizens did not conform to Prussian Imperial ideology. The building lot of the library had been donated by the city of Leipzig, while Friedrich August III, king of Saxony provided the funds for the building.
