Fulda Castle

Fulda City Palace, a Baroque edifice, in Fulda once served as the residence of prince-abbots and prince-bishops.
History+
The origins of the palace date back to the early 14th century, when an abbot's castle was built on this site. This fortification, which also contributed to the city's defense, was transformed into a palace complex in the early 17th century. In the last quarter of the same century, it underwent further reconstruction into a Renaissance palace. The palace acquired its current Baroque appearance between 1706 and 1714 under the direction of Johann Dientzenhofer.
