The oldest part of the church is the tower, dating from the middle of the 13th century. The nave is from the beginning of the 14th century, while the choir dates from the middle of the same century. There was an earlier church on the same spot, elements of which have been incorporated as building material in the presently visible church. The church is richly decorated inside with frescos dating from the Middle Ages. They depict different Christian motifs. Of the church fittings, the baptismal font (second half of 12th century) and triumphal cross (middle of the 13th century) are both medieval.
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.
