The lycée Saint-Louis traces its origins to the Collège d'Harcourt (Latin: Collegium Harcurianum).[1] The Collège d'Harcourt was founded in 1280 by Robert and Raoul d'Harcourt to offer food and housing for around forty poor students. From the beginning, it was not only a simple residence but also a place of teaching, this activity took more and more importance over time. During the Wars of Religion, it was a Catholic stronghold. As a result, Henri IV confiscated the college's property and dismissed its director. Once peace returned, the king reformed the teaching of the colleges: initially intended to train clerics and academics through theological studies, the college was transformed into an institution where the children of the nobility, Parisian bourgeois and scholarship holders from Normandy studied.

The college started to become famous in the 16th century, and great names such as Racine, Boileau and Perrault attended it in the 17th and 18th centuries.

In the 18th century, it was a stronghold of Jansenists and produced several of the philosophes and Encyclopédistes and therefore opposed the influence of the Jesuits in education, whose stronghold was located not far away, at the college of Clermont.

The original building was demolished in 1795 and the present one erected on its site in 1814.

In the course of the tumultuous 19th century, the lycée was successively turned into a prison, barracks and reformatory.

In 1812, a decree of Napoleon I ordered its reopening according to the plans of J.-B. Guynet, in order to accommodate an imperial lycée. However, it was not until October 1820 that the "Collège Royal Saint-Louis" took over from the former Collège d'Harcourt, and welcomed again boarders in 1823. In 1848, following the revolution, it changed its name to "Lycée Saint-Louis", after being called "Lycée Monge " for several months.

The lycée is primarily devoted to the instruction of science (since 1885, the boarding school only welcomed scientific students) and in classes préparatoires aux Grandes Écoles (established in 1866, the only ones present at the school since the closing of the last high school class in 1969). In 1843, a student from the school won the first prize in mathematics for the first time in the concours général. The classes préparatoires aux Grandes Écoles opened in 1866 and allowed students to take the competitive exams for the École polytechnique, the École normale supérieure (in science), Centrale, the École forestière and Saint-Cyr, and were expanded in 1885 to include preparation for the École navale.
