Vilshofen an der Donau is the largest city in the southeast of Bavaria, Germany in the district of Passau.

In 1236, Hainricus Plebanus de Vilshouen is mentioned as a pastor with a parish church.

[3] In 1241, the town was taken over by Duke Otto II of Bavaria by force after an inheritance disputes in the House of Ortenburg.

[citation needed] Therefore, it became a border town between the Duchy of Bavaria and the Prince-Bishopric of Passau.

In 1262, the city finally passed to Bavaria after Duke Henry of Lower Bavaria, the successor of Otto II, negotiated a treaty with Bishop Rüdiger of Passau after lengthy negotiations.

[citation needed] Vilshofen an der Donau is located at the confluence of the stream Vils, Pfudrach and Wolfach, south of the Bavarian Forest, a good 20 kilometers upstream of Passau.

The Danube cut into the crystalline basement here during the uplift of the Bavarian Forest in the Late Tertiary and Quaternary.

In this case, the river actively cuts into the rising mountain body, keeping pace with the tectonic uplift.

Granite was mined in the Vils-Engtal nature reserve, which was stopped in the middle of the 20th century for economic reasons.

There is also a continental impact and is characterized by sometimes very cold and snowy winters and hot and dry summers.

The occurrence of an Indian summer is therefore given annually and leads to mild temperatures in the late year.
