It was established in the ninth century to shelter the relics of bishop Lupus of Troyes, Saint Loup, the legendary defender of the city against Attila in the 5th century[1] and patron of the city.
The monastic community was reformed in 1135 by Bernard of Clairvaux, when the abbot and his monks embraced the Rule of Saint Augustine and became Canons Regular.
The Abbaye Saint-Loup, which came to be enclosed within the burgeoning medieval city of Troyes, developed a renowned library[2] and scriptorium.
The famous poet Chrétien de Troyes may have been a canon of this monastic house.
Charlemagne gave the abbey of Saint-Loup to the scholarly Alcuin,[6] and Adalelm, Count of Troyes (died 894) was a patron.
