The lords of Aarwangen were first mentioned between 1194 and 1212 as a Ministerialis (unfree knights in the service of a feudal overlord) family in service to the Kyburgs. Starting in 1266, Walter of Aarwangen was in the service of the future King of the Romans Rudolph I. Initially they owned land in the Emmental, but in 1276 they sold the land to Trub monastery. Around 1300 they built the tower of Aarwangen Castle along the banks of the Aar river. In 1313, they were firmly established in Aarwangen when Rudolf III of Neuenburg-Nidau granted them the bridge over the Aar river as a fief. After Walter's death in 1320, his son Johann took over the castle and leadership of the family. Johann was a patron of the Cistercian Abbey of St. Urban in Hasle, Lucerne and in 1341 he joined the Abbey. He remained at the Abbey until his death in 1350, which ended the Aarwangen noble line.
After the Aarwangen family died out, the castle went to the Grünenberg family. They sold it in 1432 to the city of Bern. It served as the seat of the Bernese bailiff until 1798. It is now the administrative seat of the surrounding district.
References:The Pilgrimage Church of Wies (Wieskirche) is an oval rococo church, designed in the late 1740s by Dominikus Zimmermann. It is located in the foothills of the Alps in the municipality of Steingaden.
The sanctuary of Wies is a pilgrimage church extraordinarily well-preserved in the beautiful setting of an Alpine valley, and is a perfect masterpiece of Rococo art and creative genius, as well as an exceptional testimony to a civilization that has disappeared.
The hamlet of Wies, in 1738, is said to have been the setting of a miracle in which tears were seen on a simple wooden figure of Christ mounted on a column that was no longer venerated by the Premonstratensian monks of the Abbey. A wooden chapel constructed in the fields housed the miraculous statue for some time. However, pilgrims from Germany, Austria, Bohemia, and even Italy became so numerous that the Abbot of the Premonstratensians of Steingaden decided to construct a splendid sanctuary.
