The Coteaux abbey farm was originally a seigneurial dwelling in the 16th century, before becoming part of a monastic complex.
In the 16th century, a fortified manor house with an upper and lower courtyard, barns, cellars, stables and gardens was built on this site.
Purchased by the monks in 1653, this dwelling became the abbey farm. It was part of a larger complex of monastic buildings, which has now disappeared, extending over the whole of Mont Glonne, including a tithe barn, an abbot's dwelling, monastery buildings, a cellar house in charge of food supplies and gardens.
The large porch and the surrounding wall remind us that this farm was fortified and therefore enclosed by the town's ramparts and boundary walls. Florentine legend has it that the monks built these walls to cut off the wind and stop the activity.
The farm was also known as the Porte des Mauges, as it had three openings: the large door for carts, the medium door for a rider and his horse, and the small door for men on foot.
Surrounded by vines, it also produced a renowned Muscadet, which is still grown in the area today.
