The organization of the priory is typical of Grandmont architecture, particularly in terms of the openings in the chapel and its two doors, one for the faithful and the second for the monks serving it.

The current name, Primaudière, appears in 1544 in a notarized deed, a farm lease from Maistre Jehan Dumas, his prior commendataire.

[3] The estate belonged to Jean Le Veneur, who gave it to the Abbey of Saint-Sauveur, Redon between 1061 and 1075, probably through the influence of the lord of Châteaubriant.

[4][5] Around 1095, it fell into the hands of Gauthier Hai, lord of Pouancé, who seized it "at the cost of his lance and the blood of his own and others".

[5] While the region belonged to the Duchy of Brittany, Juigné-des-Moutiers was first mentioned in 1123, when its church was donated to Brice, Bishop of Nantes.

Geoffroy agreed to grant them 10 livres of rent on the tolls of Châteaubriant and the privileges of a burgher in the town, while Guillaume de La Guerche agreed to grant 25 pounds of rent on the farms of Pouancé, and the privileges of a bourgeois in each of the towns of his seigneury, Pouancé, Segré, Martigné, and La Guerche.

[2] The monks of Grandmont then built a priory and a chapel dedicated to Notre Dame, which became a place of pilgrimage and procession on Madeleine Day.

[2] The priory's two tenant farms were responsible for providing the royal staff with oxen and charettes, particularly for transporting galley slaves.

[4] The entire convent wing (facades and roofs), as well as the former cloister square for its archaeological interest, have been listed as historic monuments since September 30, 2005.

Dating from the 13th century, it consists of a forty-meter-long vessel that terminates in the choir, abundantly lit by the three large openings in the chevet.

[2][4] The church door is the most elaborate, with two ogival archivolts separated by round moldings resting on columns with capitals.

The remaining convent buildings bear few traces of the 15th century (including a blue sandstone bay on the south gable).
