town's abbey was founded by
Guillaume Sanche lord of
Gascony in the late 10th century. According to the monastic chronicles, this was as the result of a vow he made after the battle of
Taller, in Gascony, in which he defeated the Vikings (982). In 1060, after a fire, the abbey was reconstructed on the model of
Cluny under the direction of the abbot Gregori de Montaner. The Saint-Sever Beatus was the work of monks working under the direction of the same abbot; Abbot Gregori held the post from 1028 to 1072. ==Sights==
