The Alte Nationalgalerie, a jewel in the crown of Berlin's Museum Island, stands as a testament to 19th-century art and architecture. Established in 1876, this gallery showcases a vast collection of paintings and sculptures, including masterpieces of Neoclassicism, Romanticism, Biedermeier, Impressionism, and early Modernism. As a UNESCO World Heritage site, it not only offers visitors a rich display of art but also serves as a historical monument, reflecting the evolution of museum culture over the centuries.
