The parish church is dedicated to Saint Aelhaiarn, but has sometimes been erroneously recorded as dedicated to Saint Giles, All Saints, and Saint Tysilio. The church is a very well-preserved 14th century church with an earlier tower, on the site of a pre-Norman church perhaps founded by the saint himself. There is an exceptional 14th century nave roof and a painted Tudor ceiling in the chancel. The tower of the present church dates to about 1300.
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.
