Neuburg am Inn Castle is in Neuburg am Inn near Passau in Lower Bavaria. The castle is enthroned opposite Wernstein Castle high above the Inn Valley on the border with Austria. It was once the seat of the county of Neuburg.HistoryThe castle was built in 1050 by the Counts of Formbach a few kilometers downhill from their ancestral castle. Since then they have been named after Neuburg. After their extinction, the castle came to the Counts of Andechs in 1158 before becoming the property of Bavaria in 1248. From then on, the duchies of Bavaria and Austria fought over the strategically well-situated fortress. There was a constant change of ownership. In 1310 the castle was destroyed in the Bavarian-Austrian conflict. Today's building stock comes largely from the subsequent reconstruction of the victorious Austrians. Since then, the Neuburg belonged to the Habsburgs, who pledged it until 1463, Hanns von Rohrbach acquired the castle and began the expansion, which his successor Sigmund von Niederthor continued. In 1528 the castle was given to the Counts of Salm as an imperial fief. A year later, Count Niklas II von Salm had the castle redesigned in the Renaissance style by the Passau master builder Wolf Huber and extensive gardens laid out. Only the keep, the fortifications of the outer bailey and the castle church remained untouched during the conversion work.
