The 1300 square meter princely garden is accessible from the castle courtyard. It was probably built in the 16th century, around 1700 it was refurnished. The parterre, with eight sections and a fountain, originally had four allegorical mythological figures, possibly symbols of the four seasons. Two of the original sculptures, all destroyed, were replaced with copies. The two garden pavilions on the upper terraces, probably the work of Josef Greising, also date from around 1700. The southern pavilion still has its rich, late baroque stucco decoration.
In 1937/38 the garden parterre was restored on the basis of fortress plans dating from the early 18th century to its original eight-part form with the fountain. From the Fürstengarten you also have a great view of the Main.
