Dudeldorf Castle is the most important monument in the parish of Dudeldorf. It was built in 1345 and restored 1451–53.
The original Dudeldorf Castle was built in the 12th century, although the exact date is not known. A lord of Dudeldorf is recorded in 1052. In the 14th century this aristocratic family became extinct.
The castle occupies the northern part of the village walls which also form the curtain walls of the castle. The overall site consists of the medieval tower house, which was converted into a school in the 19th century, the double-winged manor house, added in the 18th century, the courtyard with its archway and the garden and pavilion. The bergfried, which rises above a vaulted basement, bears the date 1734 at the level of the uppermost of its three floors.
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.
