Since the year 1817, Sophie was looking for a property in Paris, spacious enough to accommodate a school, a noviciate and the community. In 1820 the Society was able to purchase a very large property in the Faubourg St. Germain in Paris.

In 1806, Sophie Barat travelled to Poitiers with Henriette Girard. Here they opened the first Sacred Heart novitiate with Lydie Chobelet, Josephine Bigeau, and Thérèse Maillucheau.

After the foundation of the Society in Amiens, the community of Sophie Barat and her companions merged with the Visitation Sisters’ community of St. Marie d’En Haut in Grenoble.

On October 17, 1801 in Amiens, Saint Madeleine Sophie Barat and two companions founded the first Community and first School of the Society of the Sacred Heart, officially founded on November 21, 1800 in Paris, in rue de Touraine (Maison Duval).
