The Saint-Philbert-de-Grand-Lieu abbey was constructed around 815 on the lands of a former estate called Déas, which were given to the monk Saint Philibert in the 7th century. It was affiliated with the Abbey of Noirmoutier and served its needs. The construction was authorized by Louis I, the son of Charlemagne. This location was chosen because it was more protected from Viking raids, being further inland. Indeed, the Abbey of Noirmoutier had been attacked by the Normans multiple times during the first half of the 9th century.
During the 14th century, a wooden bell tower was erected above the entrance porch of the abbey. During the religious wars in the region, the Huguenots also caused damage to the site. They notably damaged the choir, the porch, and the bell tower. In the 17th century, the church became a parish church. Later, during the French Revolution, the abbey was sold as national property in 1791. During the Vendean uprisings, the building was used by the republicans as a fodder shed and a munitions depot.
After the construction of the new parish church in 1869, the abbey served as a covered market, and the cracked walls had to be reduced in height by 3 meters. However, the discovery of the tomb in 1865 eventually renewed interest in the site, and restoration work was carried out between 1898 and 1904. Consequently, the abbey has been classified as a historical monument since 1896, even though it was no longer in use. It was only in 1936 that it was returned to religious use. In the same year, a celebration marked the 1100th anniversary of the transportation of the relics to the town, and a relic of Saint Philibert was placed in the sarcophagus. The monument is now open to visitors, with approximately 9,000 visitors per year. In addition to tours of the building and gardens, artistic and cultural exhibitions are held within the abbey. Religious ceremonies are occasionally celebrated, including the 'Feast of Saint Philibert' with a vigil and a patronal Mass.
The abbey is predominantly in the Carolingian style, but modifications over time have incorporated elements from other styles, including Romanesque. The building has also undergone changes in its visual appearance, both on the exterior and interior.
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.
