Hilgartsberg Castle lies on a mountain on the left bank of the Donau River. It was first mentioned in 1112. It was a fief of the Bishop of Bamberg and cared for by the Counts of Sulzbach. When the counts died out in 1188 the castle fell to a couple of sons of Frederick I, Holy Roman Emperor. They lent it out to Walchunus von Kamm.
In 1326 the castle came into the hands of the House of Eck. When Peter Ecker von Eck fell out of favor with Duke Albrecht I of Bavaria, the castle was besieged and conquered by the Duke in 1357. Albrecht then strengthened the castle and installed a castellan. Later it was lent out to several nobles. In 1617 it was used by the Fugger family, who considerably enlarged the castle after a big fire had damaged it in 1626.
In 1704, during the War of the Spanish Succession, Hilgartsberg Castle was occupied by Austrian troops. In 1742, during the War of the Austrian Succession, the Austrian troops returned and with help of Hungarian troops conquered and burned down the castle. After that it was a ruin and was never rebuilt.
Later the ruins were owned by a local brewer and the Bavarian State. And in the 1970s part of it served as the village school. At present Hilgartsberg Castle can freely be visited. It is used as a venue for cultural events.
References:Vufflens castle was built in 1425 on the site of a previous medieval castle by Henri de Colombier. It is the most significant example of a small group of fortified Romandy castles from the middle ages, characterised above all by its brick construction. In 1530, it was set on fire by Bernese troops. In 1641 it was acquired by the de Senarclens family. The castle is currently privately owned and cannot be visited.
