Obernberg Castle

Obernberg Castle is a hilltop castle in the eponymous municipality in the district of Ried im Innkreis in Upper Austria.
The first castle complex was built by the Counts of Formbach in the 10th century. They had the castle managed by a castellan. A Meginhart de Obernberge is documented from the year 1160. In 1191, Obernberg was ceded to the Diocese of Passau by the Counts of Formbach and their successors, the Counts of Andechs. Bishop Wolfker had Obernberg expanded into an almost impregnable fortress between 1199 and 1202. In 1241, the Muhringers from Eberschwang attacked the fortress and market of Obernberg. Duke Friedrich II of Austria was able to capture the castle in 1243 after a siege through treachery. The castle's guard was transferred to the Counts Ulrich and Wernhart of Schaunberg. They were able to withstand a six-week siege by the Passau bishop Rüdiger, who was allied with Duke Otto of Bavaria, in 1245. In 1246, Duke Friedrich returned the castle to the Diocese of Passau, which was then occupied by Duke Otto. When Otto of Lonsdorf was elected as the new Bishop of Passau, the castle reverted to Passau and remained with the diocese until the secularization in 1803. A large fire broke out in Obernberg in 1368. Obernberg was pawned to Bavaria in 1368, in 1372 it was pawned for four years to the Archdiocese of Salzburg after an attack by Reichker of Riedenberg and Zacharias Haderer, in 1388 it was with Duke Albrecht III for some time, and in 1411 it was pawned to the Ezzelin Counts of Ortenburg. A Kuchler, who managed Obernberg around 1427, introduced a toll in 1466.
