Grünau Castle is the gift of Duke Otto Henry, the Duke of the Duchy of Pfalz-Neuburg, to his wife Suzanna of Bavaria. The white-stone hunting lodge in the Renaissance style with three towers was built in the middle of the XVI century. The finishing of the upper floors was entrusted to the famous Jörg Broyu youngest of Augsburg, whose frescoes have survived to these days.
The castle complex also includes a chapel of the XVII century. The castle belongs to the Wittelsbach Foundation and is used as a cultural center. It hosts garden parties in May, Christmas markets in December, and concerts year-round.
