Marienberg Fortress (German: Festung Marienberg) is a prominent landmark on the Main river in Würzburg Germany. The mighty Fortress Marienberg is the symbol of Würzburg and served as a home of the prince-bishops for nearly five centuries. It has been a fort since ancient times. After Gustavus Adolphus of Sweden conquered the area in 1631 the castle was reconstructed in the Baroque style. Today it is a park and museum.
