Story:
A small castle was built in the 12th century to secure the river crossing on the military road leading to the eastern state border. Walther von Swabdorf is the first reference to a manor house around 1182. Schwadorf was sovereign, but it came to Bishop Wolfger von Passau as early as 1194 in an exchange. In 1215 the then Hofmark was granted blood jurisdiction by Emperor Friedrich II. In 1220, Eberhard von Schwadorf was one of the ministerials of Duke Heinrich the Elder. Ä. from Modling. In the 14th century the castle was mortgaged several times, for example in 1381 to Albrecht von Puchheim. As late as 1383, Schwadorf is referred to as the free property of the Passau bishops.
However, the sovereign retracted it two years later. In 1398 it was again owned by the diocese, which gave it to Dukes Wilhelm and Ernst as dowry. In the late 15th century, the dominion was pledged to King Matthias Corvinus, which meant that the castle was confiscated by King Maximilian I in 1490. In 1494 it was handed over again to the diocese of Passau. With a few interruptions, she remained with the bishops of Passau until 1806. Today's Renaissance castle was built around 1600. When the diocese had to give up its Austrian possessions, Schwadorf was taken over by the state and sold to private individuals in 1826.
These included the knights Fellner von Feldegg (1823) and Theodor Ritter Riedl von Riedenau (1879). dr Arnold Segal bought the estate in 1926. A year later, a severe earthquake caused significant damage. After Segal was expropriated in 1938 and the castle was handed over to the German Settlers Society, he received his property back after 1945. Most recently, the castle and estate belonged to the Auer-Welsbach family. The building, which has not been restored for many decades, was uninhabited and left to decay until a few years ago. The rescue came from a new owner, who has now largely restored the residential building.
