Gnandstein castle was built in the Romanesque style in the 13th century, probably only with a rectangular groundplan and a residential tower. Parts of the present building still date from this early period. The external walls were extended several times.
During the Thirty Years' War the castle was attacked by Swedish troops and partly destroyed. Shortly before the end of the war the south wing burned down after being struck by lightning.
The well house is more than 33 meters high, giving the visitor a broader view of the region. It was used as a watch tower. Guided tours are available.
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.
