Herzog Anton Ulrich Museum

The current museum building, designed by architect Hermann Eggert, was opened in 1887. The structure underwent significant changes in the 20th and 21st centuries. In 2010, an extension was added to the museum park behind the main building, providing 4,000 square meters of new exhibition space across three floors. From 2013 to 2016, the historic main building underwent a comprehensive renovation to restore it to its original state while integrating modern exhibition technology. The museum was reopened in the renovated main building on October 23, 2016, following a seven-year construction period.

The museum houses an important collection of Western European art, with a particular strength in Flemish and Dutch paintings from the 16th to 18th centuries. The collection also includes significant French paintings and works from other European schools. The holdings were significantly enriched by the ducal collections, which focused heavily on landscape paintings and genre scenes. The museum also holds a notable collection of medieval objects, which are currently housed in a separate location, the Burg Dankwarderode, as part of the broader 3Landesmuseen Braunschweig network.

The Print Room was founded as part of the original 1754 'Ducal Art and Natural History Cabinet' by Duke Carl I of Brunswick and Lüneburg, incorporating older ducal graphic collections. It holds a significant collection of European graphic arts from the late Middle Ages to the present, with a strong emphasis on Dutch and German schools, followed by Italian works. The collection includes a notable group of Japanese color woodcuts and works from North America in the 20th century. A major acquisition occurred in 1910 through the bequest of the Brunswick graphic collector, significantly expanding the holdings of 15th to 19th-century prints.

As one of the oldest public museums in Europe, the Herzog Anton Ulrich Museum holds a unique place in the history of museology. Its founding in 1754 predates many other major European public institutions, marking an early commitment to making art accessible to the public rather than keeping it within private ducal chambers. The museum's continuous operation and expansion, including recent major renovations and the addition of modern exhibition spaces, demonstrate its enduring relevance. It remains a key cultural landmark in Brunswick, preserving the artistic legacy of the region and serving as a vital center for art historical research and public education.
