The Altes Museum (English: Old Museum) is a listed building on the Museum Island in the historic centre of Berlin and part of the UNESCO World Heritage. Built from 1825 to 1830 by order of King Frederick William III of Prussia according to plans by Karl Friedrich Schinkel, it is considered as a major work of German Neoclassical architecture. It is surrounded by the Berlin Cathedral to the east, the Berlin Palace to the south and the Zeughaus to the west. Currently, the Altes Museum is home to the Antikensammlung and parts of the Münzkabinett.

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.
