A church at the site of current Basilica of San Maurizio is documented since 1078, when the bishop of Turin, Cuniberto, acknowledges the donation of this and other churches to a monastery in Pinerolo.
The documents also refer to an arduous major reconstruction starting in the 1440s and completed sometime in the early 17th century, when the nave was finally roofed. The new church was reconsecrated in 1635. Sometime around 1665, damage to the church was caused by lightning strike, but even more dramatic an explosion near the monastery of St Clare in Pinerolo killed 400 townsfolk, who were initially brought to the church awaiting burial. The mass of cadavers led to a closure of the church. In 1691, the church was used to store grain in expectation of a siege of the town. Some damage occurred to the church during a siege two years later.
The bell-tower, dating 1336, was built in a Romanesque style. The interior of the church contains frescoes depicting the Ascension of Christ by Giuseppe Antonio Petrini and the main altarpiece canvas depicting the Birth of the Virgin by Claudio Francesco Beaumont. The church was again restored in 1897, including frescoes by Gabriele Ferrero. The church has numerous side chapels. It was raised to a minor basilica in 2002.
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.
