Around the third quarter of the 12th century Freiherr von Weissenburg donated land along the Simmen river to the Augustinian order for a monastery. The monastery was first mentioned in 1228 along with the surrounding village. In 1368 the Freiherr von Brandis inherited the Weissenburg lands including patronage of the monastery. It continued to expand during the 13th and 14th centuries as nobles donated lands and the monastery bought estates.
The monastery church of St. Mary became the burial church of the Freiherrs. In 1439 the city of Bern acquired the Weissenburg lands including the monastery and the village. In 1486 they forced the monastery to accept the authority of the college of canons of the Cathedral of Bern. In 1528, Bern adopted the new faith of the Protestant Reformation and secularized the monastery. The monastery church became the parish church of newly created parish.

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.
