Prince Alexander von Thurn und Taxis built a Chinese tower in his palace garden in 1842. In 1902, he was brought to the new summer residence at Castle „Prüfening“ in Regensburg. In 1998 a sponsoring association was founded, which brought the Chinese Tower back to Donaustauf, restored it and finally reopened it on September 17, 1999. The tower is only open for special events.
