Ortenburg-Neuortenburg
Ortenburg-Neuortenburg was a minor county and Imperial State in present-day Lower Bavaria, Germany. It was located on the lands around Ortenburg Castle, about 10 km (6.2 mi) west of Passau. Though the Counts of Ortenburg - formerly Ortenberg - emerged in the 12th century as a cadet branch of the Rhenish House of Sponheim (Spanheim) who then ruled over the Duchy of Carinthia, an affiliation with the Carinthian Ortenburger comital family is unverifiable.
