The Georgsberg (also St. Georgsberg , Jörgenberg or colloquially Oberhausberg ) is a mountain on the headland between the Danube and Ilz in the city of Passau in Bavaria. The mountain was named after a chapel on the mountain that was dedicated to St. George . The mountain has an approximate height of 420 m above sea level. NN along the ridge, which essentially runs along the Rennweg road .
The border between the Passau districts of Hals and Altstadt runs partly on the Georgsberg. On the mountain is the fortress Oberhaus and directly at the confluence of the Danube and Ilz the fortress Niederhaus .
The Georgsberg belongs to the Bohemian mass , which consists of crystalline rocks, mainly granites and gneiss . Due to the tectonic clod in the Upper Devonian to the Upper Carboniferous, tectonic fault zones developed in this rump mountain range. A fault zone south of the pile runs through the Georgsberg. This disturbance then continues almost parallel to the Danube to the Schlögener Schlinge in Upper Austria. The Georgsberg consists largely of schisty pearl gneiss , a rock that is typically bound to geological shear zones.
The Ilz breakthrough road tunnel runs through the Georgsberg. This two-tube tunnel was completed in 1947 and repeatedly enlarged and modernized in the course of the road expansion. Plans for a separate pedestrian and bicycle tunnel were drawn up in 2012. It would have been the third tunnel through the Georgsberg in this area. On April 28, 2013, this 116-meter-long tube was in a referendum rejected because of vorveranschlagten high construction costs of at least 2.5 million euros.
