The old town of Avigliana is one of the most significant in Piedmont, for its medieval architecture and its churches. The castle was probably built in 942 by the Marqueses Arduinici of Turin (it was probably Arduino the Hairless who built the first settlement of Castrum Avilianae) on the top of Mount Pezzulano. This castle was used by the Counts of Savoy at least from 1137. In 1691, after conquering it, the French Marshal Catinat got it definitively demolished, leaving the remains we can see after a pleasant walk from Piazza Conte Rosso.
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.
