The church on the site of current San Dalmazzo is documented from the 11th century, but the present church was reconstructed in 1702. In 1885 the interior was redecorated in neo-gothic style. Adjacent to the church is the former convent and school of the Barnabite order. From 1271 to 1606, the church had been linked to the Order of Canons Regular of Sant'Antonio of Vienne, but then was transferred along with the convent to the Barnabites.
The nave was painted by Enrico Reffo in 1895–1916. The interior also contains 18th century canvases and an antique baptismal font.
Between 1629 and 1631 the chapel of the Madonna of Loreto was built, imitating the Casa Santa (Holy House), which contains an icon related to Marian Apparitions.
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.
