The Saint-Pierre Abbey in Airvault was initially a collegiate church of regular canons of Saint Augustine, founded around 990 by Audéarde, wife of Viscount Herbert I of Thouars. As the canons were lax in following the rules of the Order of Saint Augustine, the Bishop of Poitiers decided to send a monk from the Augustinian abbey of Lesterps in Limousin to reform it. Pierre de Fonte Salubri (of Saine Fontaine) was appointed the first abbot of Airvault in 1096 and died on August 7, 1110. He undertook the construction of the abbey church. According to the Chronicle of Saint-Maixent, the church was consecrated in 1100 but subsequently underwent modifications and additions.
After the creation of the diocese of Maillezais in 1317, transferred to La Rochelle in 1648, the abbey became dependent on it.
During the Revolution a road was pierced through the abbey separating the convent buildings of the abbey. Several buildings are still visible as the room called the 'vat', the 'prison' (fortified gate), underground rooms, the fourteenth-century chapel and especially the abbey house which has hosted since 1975 the municipal museum.
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.
