Festung Marienberg, situated on the banks of the Main river, dates back to the early 13th Century. One of the most beautiful examples of the Baroque style of architecture, this fortress is a premier attraction in the city of Wurzburg. The castle atop the fortress has served as the residence of both bishops and royalty throughout the centuries. The fortress, which sits amidst serene vineyards, was seized during the Napoleonic Wars and World War II. Festung Marienberg houses the Mainfränkisches Museum, which features a delightful collection of sculptures and pieces of Franconian art. Visitors to the fortress can also explore the Princes' Building Museum, which houses elegant furniture, paintings, the Princes' Hall, which is an esteemed concert venue and the tranquil Princes' Garden.
