The diocese of Auxerre (Latin: dioecesis Antissiodorensis) is a former French Roman Catholic diocese. Its historical episcopal see was in the city of Auxerre in Burgundy, now part of eastern France. Currently the non-metropolitan Archbishop of Sens, ordinary of the diocese of Sens and Auxerre, resides in Auxerre.
The Church of Saint-Germain l'Auxerrois (French pronunciation: [sɛ̃ ʒɛʁmɛ̃ losɛʁwa]) is a medieval Catholic church in the 1st arrondissement of Paris, directly across from the Louvre Palace. It was named for Saint Germanus of Auxerre, a medieval bishop of Auxerre, who became a papal envoy and met Saint Genevieve, the patron saint of Paris, on his journeys. Genevieve is reputed to have converted Queen Clotilde and her husband, French king Clovis I to Christianity at the tomb of Saint Germain in Auxerre.
The current church was built in the 13th century, with major modifications in the 15th and 16th centuries. From 1608 until 1806, it was the parish church for inhabitants of the Louvre, and the church contains the tombs of many notable artists and architects who worked on the palace. During the reconstruction following the Notre-Dame fire on the nearby Ile de la Cite, the cathedral's regular services have been moved to Saint-Germain l'Auxerrois.
Germanus of Auxerre (Latin: Germanus Autissiodorensis; Welsh: Garmon Sant; French: Saint Germain l'Auxerrois; c. 378 – c. 442–448 AD) was a western Roman clergyman who was bishop of Autissiodorum in Late Antique Gaul. He abandoned a career as a high-ranking government official to devote his formidable energy towards the promotion of the church and the protection of his flock in dangerous times, personally confronting, for instance, the barbarian king Goar. In Britain he is best remembered for his journey to combat Pelagianism in or around 429 AD, and the records of this visit provide valuable information on the state of post-Roman British society. He also played an important part in the establishment and promotion of the Cult of Saint Alban. The saint was said to have revealed the story of his martyrdom to Germanus in a dream or holy vision, and Germanus ordered this to be written down for public display. Germanus is venerated as a saint in both the Catholic Church and Eastern Orthodox Church, which commemorate him on 31 July.
The principal source for the events of his life is the Vita Germani, a hagiography written by Constantius of Lyon around 480, and a brief passage added to the end of the Passio Albani, which may have been written or commissioned by Germanus. Constantius was a friend of Bishop Lupus of Troyes, who accompanied Germanus to Britain.
The Abbey of Saint-Germain d'Auxerre is a former Benedictine monastery in central France, dedicated to its founder Saint Germain of Auxerre, the bishop of Auxerre, who died in 448. It was founded on the site of an oratory built by Germanus in honor of Saint Maurice.
