The Gemäldegalerie Dachau holds the town's art collection, focused on the works of the Dachau School — the artists' colony that flourished here from the 1870s to the early 20th century. The painters who gathered here, including Carl Spitzweg, Ludwig Dill, Arthur Langhammer, and Adolf Hölzel, were attracted by the distinctive quality of light over the moorlands. Their landscapes capture a now-vanished agricultural world: the flat meadows, the willows, the working farm life of late 19th-century Bavaria.
The collection provides an important counterpoint to the concentration camp memorial nearby — a reminder that the name Dachau had an entirely different set of associations before 1933. The gallery occupies a period building in the old town, a short walk from the castle. Opening hours vary by season.
