The institution was founded by the Company of Mary Our Lady in 1607 by Jeanne de Lestonnac (1640).

She was the niece of the writer Montaigne, who spoke of her in these terms: "very pious, cheerful, intelligent and beautiful, nature made her a masterpiece, combining such a beautiful soul with such a beautiful body and housing a princess in a magnificent palace."

Through the foundation of the Company of Our Lady, she put all her human and spiritual riches at the service of the young women of her time. Her optimistic vision of Man leads to a pedagogy whose deep purpose is to detect, welcome, awaken and stimulate all potentialities. Concerned with serving in each child the Man, son of God.

Trust in life and in God gave impetus to the Company of Our Lady. Starting in Bordeaux, it spread very quickly and crossed borders. In a society to be rebuilt, many cities in the South-West called upon Jeanne de Lestonnac and her daughters: their apostolic fervor grew stronger and their schools multiplied.

Thus, our Jeanne d'Arc school was created in Carcassonne. It then brought together a nursery, primary and middle school.

They form a Catholic Educational Institution, Under Contract of Association with the State (Debré Law 1959). The institution's mission is to provide quality education, bringing rigor, culture and a taste for work to students.

The institution (Saint-Stanislas) was founded in 1813 by Abbé André Delmas, in the Ursulines Convent where it is still located today. Some rooms bear witness to this, such as the common room which is probably the former chapter house.

A minor seminary until 1907, when it was expropriated, the school was able to reinstall itself in its premises as a secondary college and took the name of Saint-Stanislas.

First a college then a boys' high school, Saint-Stanislas followed the evolution of the school world to become a mixed high school in 1969, then a general and technological high school and finally a comprehensive high school.
