The Abbey of Saint-Savin-en-Lavedan was a Benedictine abbey in the commune of Saint-Savin and one of the most important religious centres in the County of Bigorre. The abbey dates at least from the 10th century, and it was built by order of Charlemagne on the site of an ancient Gallo-Roman fortress. In 841, the abbey was looted and burnt by the Normans, and previously by the Saracens.
In 945, Count Raymond I of Bigorre gave the abbey a generous endowment consisting of a territory known as the Pascal de Saint-Savin, which was made of the eight villages. The church of Saint-Jean-de-Saint-Savin became their communal church.
In 1080 the abbey was united to the Abbey of St. Victor, Marseille. In 1130 Bernard d'Arcizas and Centule II, Count of Bigorre, confronted the abbot and the inhabitants of the Val d'Azun over a burial. Queen Marguerite of Navarre (1492–1549) took refuge in the abbey from a flood. From the thirteenth century, the abbey still controlled the territory of seven villages.
From the 16th century the abbey suffered due to the destruction associated with the French Wars of Religion and relaxed its discipline, although there were attempts to restore it in the 17th century by the monks of the Congregation of St. Maur.
Only three monks remained living in the abbey in 1790. In the following year, the church and the monastic buildings were converted for the use of the parish. Part of the abbey was sold for a stone quarry and the chapter house became a stable. In 1854, a strong earthquake caused further destructions. Prosper Mérimée took charge of its restoration in 1855.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
