The Altes Museum (German for Old Museum) is one of several internationally renowned museums on Museum Island in Berlin, Germany. Since restoration work in 1966, it houses the Antikensammlung (antique collection) of the Berlin State Museums.The museum was built between 1823 and 1830 by the architect Karl Friedrich Schinkel in the neoclassical style to house the Prussian royal family's art collection. The historic, protected building counts among the most distinguished in neoclassicism and is a high point of Schinkel's career.Until 1845, it was called the Königliches Museum (Royal Museum). Along with the other museums and historic buildings on Museum Island, the Altes Museum was designated an UNESCO World Heritage Site in 1999. In the early nineteenth century, Germany's bourgeoisie had become increasingly self-aware and self-confident. This growing class began to embrace new ideas regarding the relationship between itself and art, and the concepts that art should be open to the public and that citizens should be able to have access to a comprehensive cultural education began to pervade society. King Friedrich Wilhelm III of Prussia was a strong proponent of this humboldtian ideal for education and charged Karl Friedrich Schinkel with planning a public museum for the royal art collection. Schinkel's plans for the Königliches Museum, as it was then known, were also influenced by drafts of the crown prince, later King Friedrich Wilhelm IV, who desired a building that was heavily influenced by antiquity. The crown prince even sent Schinkel a pencil sketch of a large hall adorned with a classical portico. Schinkel's plans incorporated the Königliches Museum into an ensemble of buildings, which surround the Berliner Lustgarten (pleasure garden). The Stadtschloss in the south was a symbol of worldly power, the Zeughaus in the west represented military might, and the Berliner Dom in the east was the embodiment of divine authority. The museum to the north of the garden, which was to provide for the education of the people, stood as a symbol for science and art—and not least for their torchbearer: the self-aware bourgeoisie.
