Weißenborn Castle was first mentioned in a document in 1213 together with the village of the same name. Weißenborn was given to the Freiberg family von Hartitzsch as a fief in 1365, and it remained in their possession until 1802. The castle was built probably in the 14th century. Weissenborn was also not spared from wars, looting and the plague.
In 1802, Alexander von Hartitzsch sold the castle and manor to Christoph Schubert, who passed both on to a cavalry master from Weißenbach . Colonel Freiherr von Wangenheim acquired the manor from Count Hohenthal-Püchau in 1882 and kept it until 1924. In 1931, Dr. Otto Fritz new owner of the manor and expropriated in 1945. During the GDR era there was a culture house in the premises. Weissenborn Castle has been privately owned again since 2010.

Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner.
