History
Collège d'Harcourt

The Lycée Saint-Louis, formerly known as the ''Collège d'Harcourt'' (),
was established in 1280 by Robert and Raoul d'Harcourt with the intention of providing food and lodging to approximately forty students from disadvantaged backgrounds. From its beginning, the institution was not only a residence for students but also a centre of learning, a role that gradually gained prominence. During the
Wars of Religion, it emerged as a bastion of Catholicism, prompting Henri IV to confiscate the college's assets and remove its head. Once peace returned, the king restructured the educational framework of the colleges: originally designed to educate clerics and scholars in theological disciplines, the Collège d'Harcourt was transformed into an establishment where the children of the gentry, the Parisian bourgeoisie and scholarship recipients from Normandy received their education.
In the 16th century, the college began to gain significant recognition. The 17th and 18th centuries saw the attendance of great historical figures such as
Racine,
Boileau and
Perrault.
In the 18th century, the college became a bastion of
Jansenists and produced several prominent ''
philosophes'' and ''
Encyclopédistes

Lycée Saint-Louis
In 1812, a decree from Napoleon I mandated the reopening of the Collège d'Harcourt according to the plans of J.-B. Guynet in order to accommodate an imperial lycée. However, the institution was reestablished as the "Collège Royal Saint-Louis" only in October 1820 and it resumed accepting boarders in 1823. After the
French Revolution of 1830, the college briefly operated under the name "Lycée Monge" before officially becoming "Lycée Saint-Louis".
The lycée is primarily devoted to the instruction of science (since 1885, the boarding school has exclusively admitted students pursuing scientific studies). The scientific
classes préparatoires aux Grandes Écoles, a programme that was established in 1866, has been the sole academic focus of the institution since the discontinuation of its high school classes in 1969. In 1843, a student from the school achieved a notable milestone by winning the first prize in mathematics at the

Academics
The school offers mainly scientific courses including MPSI (Mathematics, Physics, Engineering), PCSI (Physics, Chemistry and Engineering) for the first-year students, and MP (Mathematics, Physics), PC (Physics, Chemistry), PSI (Physics, Engineering) for final-year student as well as BCPST (Biology, Chemistry, Physics, Geology).

The lycée Saint-Louis, like its neighbours the lycées
Louis-le-Grand and
Henri IV, commonly known as
"the three Lycées of the Sainte-Geneviève hill", is renowned for its selectivity, the quality of its teaching and its results in the various competitive examinations.
Campus
The school features a ² library, which is accessible to both boarders and day students until 10:15 p.m. It also offers a mixed dormitory with 356 beds, including 234 single rooms and 61 double rooms, as well as a chapel. In addition to a dining hall, the school provides a cafeteria, and classrooms are available for student use outside their scheduled hours.
The campus is equipped with sports facilities, including a sports field and two multi-sport gymnasiums for activities such as ultimate frisbee, basketball, volleyball, and badminton. Other amenities include a gym, a billiard room, and a climbing wall. Students are required to engage in two hours of sports per week, with additional access to the sports facilities provided by the sports association at noon and in the evening.
