Saint Gertrude's was an Augustine abbey, limited to 12 canons of noble descent. The church was built from the 14th to the 16th century. The tower has an openwork spire, dating from 1453. Inside is an 18th century carillon.
The abbey was closed in 1796 (during French occupation) and the buildings got other uses. In 1919 it became a Benedictine abbey. Reconstructions were carried out after the fire during World War II. The abbey grounds (compound outside the church) at present has mixed uses, and is like a little pleasant park to hang out or have a quiet rest.
During the second world war, the church (as many others in Leuven) was seriously damaged. The artistic choir stalls seemed beyond repair. Fortunately photographs existed. After the war, the stalls were recreated by sculptors, who did an excellent job. The choir with its many wooden sculptures is now one of Leuven's most outstanding works of art. One can distinguish between original parts and later parts by judging the colors of the wood, the older parts being darker.
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.
