St. Nicholas Church is a large, cruciform town church set on Place Dalton at the heart of the lower town which clusters below the walls of the citadel. Due to the destruction of the French Revolution, WWI and WWII it is the most significant surviving medieval building in the town.
The church is first mentioned in 1208 as a foundation of the Abbey of Notre-Dame within the citadel, a relationship which existed into the 16th century. About this time, the silting up of one of the channels caused the centre of the town to move southwards, and St Nicholas took over from St Peter as the main town church.
The vaulted roofs in the nave and transepts were installed in the 17th century, but their weight caused the walls to crack, and as part of the rebuilding the nave was widened and lengthened, a response to the doubling in population of the lower town that century.
All the glass was destroyed during the liberation, and has so far been replaced in the lower stories with some splendid 1980s abstract designs.
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.
