Up to twenty archaeologists from the Local Archaeological Department attended the season of archaeological digs conducted from May 2009 to February 2010.
This project met three different expectations :
- Restoring the levels of medieval floors discovered during the studies of 2006,
- Discovering the remains of the buildings that made up the priory,
- Studying the tombs of the clergymen and lay people buried in different cemeteries.
Several elements about the priory’s origin were uncovered during this event:
- The remains of a church from the year one thousand and its monastic buildings that made up the original monastery,
- The remains of buildings assigned by the cloister that hosted the religious community who followed the Rule of St. Augustine,
- Nearly 420 tombs of clergymen and lay people including women and children buried between the 12th and 18th century,
- Various objects belonging to the community, often from a funerary context,
- The truth about the geographical area around the priory, which was an island of the Loire until the late 16th century.
