Fürstenbaumuseum, Regional art museum at Marienberg Fortress in Würzburg, Germany

The Fürstenbaumuseum occupies the eastern wing, the Fürstenbau, of Marienberg Fortress above Würzburg and forms part of the Museum für Franken. Its first floor holds the prince-bishops' living quarters with furniture, paintings and carpets from the Renaissance to the Baroque, including the Fürstensaal with the Echter family carpet. The second floor presents Würzburg's city history from the early Middle Ages to 1945.

A first museum display was installed in the east wing of Marienberg Fortress in 1938 but closed shortly afterwards because of the war. The Fürstenbaumuseum opened in its present form on 11 October 1990, combining the prince-bishops' living quarters on the first floor with the city history department on the second. It has been closed since 2021 for restoration work on the fortress.

The collection displays works by sculptor Tilman Riemenschneider and other pieces that show how Franconian artists created over centuries. These objects reflect the artistic traditions and skills that developed in the region through different time periods.

The Fürstenbaumuseum has been closed since 2021 because of restoration work on Marienberg Fortress, so it cannot currently be visited. The two floors are reached by stairs, including the Echtertreppe and the Bibratreppe, and the rooms are spread across the east wing.

The collection includes detailed city models showing how Würzburg changed architecturally across different historical periods. These models allow visitors to see the city's development in miniature form.
