In 1910 during the restoration of Angerdshestra church 30 old pergaments were found revealing that the old church was inaugurated in the 13th century. Today documents are located in Stockholm Historical Museum. The current church was made of wood in 1669 to the site of medieval church. It was enlarged and restored in the 18th century. The oldest artefact is a wooden sculpture of St. Anne, dating from the 15th century. The altar was probably painted by Johan Kinnerus between 1716-1717.
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.
