Origin and history

Trizay Abbey, founded in the 12th century by monks of Pontigny Abbey, is a former Cistercian abbey located in Bournezeau, Vendée. Its exact origin remains uncertain, with sources referring to 1117, 1125 or 1132 as possible dates. It is established thanks to donations from Hervé de Mareuil, Geoffroy de Tiffauges and Pierre L'Evêque, under the impulse of Guillaume, bishop of Poitiers. The abbey church was consecrated on August 15, 1145. Its name, Sancta Maria de vado Trisagii ("Holy Mary of the ford of Trizay"), reflects its strategic position near the Lay River, an essential crossing point.

The abbey thrives thanks to agriculture and the control of irrigation, as evidenced by the book The Principles of the Cultivator of Dom Le Rouge, a monk of Trizay. At its peak, it owns up to 100 hectares of land, farms and woods, and founded around 1156 an abbey-daughter on the island of Ré, Notre-Dame-des-Châteliers. However, it suffered heavy damage during the Hundred Years' War (destruction of the capitular hall and cloister) and the Wars of Religion. In 1568, the Protestant Jean Bras de Fer ransacked it, marking the beginning of an irreversible decline.

A restoration was undertaken in 1770 by Abbé René-Claude de La Roche Saint-André, as indicated by the southern pediment (DLBP ANNO 1770), but the Revolution interrupted the work. In 1790, only five monks remained; The abbey was dissolved and its buildings transformed into a farm in the 19th century. Two historical inventories remain: a stocktaking of Protestant ruin (1570) and a state of property of 1790. Today, only the abbey church, remains of the east wing, an 18th century building and cloister floor have been protected as historical monuments since 1989.

The abbey of Trizay, daughter of Pontigny (one of the five Cistercian mother houses) and sister of the abbey of the Star, extended its influence on eighteen surrounding parishes. Its hydraulic network, including a canal and a mill carried away by a flood in 1770, illustrates the ingenuity of the monks. Private property until 2019 (Cottencin-Debailleux family), it embodies a religious and agricultural heritage marked by conflicts and reconstructions.

It should not be confused with the Benedictine priory of Trizay in Charente-Maritime, often mistakenly called "Trizay Abbey". The elements protected today include the remains of the church, the convent wing, an 18th century building and the floor of the cloister, fragmentary witnesses of its glorious past.
