Which neoclassical museum on Berlin's Museum Island houses 19th-century art?

The Alte Nationalgalerie is the neoclassical museum on Berlin’s Museum Island that houses major collections of 19th-century art.

The gallery was built between 1862 and 1876 for King Frederick William IV of Prussia. Friedrich August Stüler prepared the main design, with Heinrich Strack carrying out the work and later details. Its architecture combines late Neoclassicism with early Neo-Renaissance elements.

The building was conceived as more than a container for art: its temple-like exterior, theatrical grand staircase, and church-like apse were intended to symbolize the unity of art, nation, and history. An equestrian statue of Frederick William IV stands above the entrance stairs.

Visitors often confuse the gallery with the Altes Museum, Neues Museum, or Pergamon Museum because all are part of Museum Island. Their collections differ. The Alte Nationalgalerie is especially associated with 19th-century Neoclassical, Romantic, Biedermeier, Impressionist, and early Modernist works, including paintings by Caspar David Friedrich, Édouard Manet, and Adolph von Menzel.
