St. Lorenz Basilica is a baroque minor Basilica and the former abbey church of the Benedictine Kempten Abbey. A church was built on the site in the 13th century but was burned down in 1478.
Roman Giel of Gielsberg, the Abbot of Kempten, commissioned the master builder Michael Beer from Graubünden to build a new church to serve the parish and monastery. The foundation stone of the Basilica of St. Lawrence was laid on 13 April 1652. This was one of the first large churches built in Germany after the end of the Thirty Years' War.
Michael Beer built the nave, the ground floor of the towers and the choir. He was succeeded by Johann Serro on 24 March 1654. The church was consecrated on 12 May 1748.
In 1803 the monastery was dissolved and the church became a purely parish church. In 1900 the twin towers were finally completed. They were build of concrete which is heavier than the used material before that time. Cracks at the connections to the main building are the result of the completed towers.
In 1969 Pope Paul VI bestowed the honorary title of basilica minor.
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.
