About Lycée Saint-Marc
Lycée Saint-Marc is a private Catholic school located in Lyon, in the Rhône department of France. Situated on the slopes of the Croix-Rousse district, the historic area that gave the institution its name, it has been part of the Lyon educational landscape for many generations. Its founding is rooted in a tradition of denominational education carried forward by a religious congregation, a heritage that continues to shape its pedagogical identity and educational project.
The institution offers schooling across several levels of secondary education, from middle school through high school, allowing families to enrol their children within a continuous educational path over several years. It operates under contract with the French state, placing it within the general framework of national education while retaining a distinctive character linked to its Catholic identity. The academic curriculum is complemented by educational, cultural and sporting activities that supplement traditional classroom instruction.
Lycée Saint-Marc positions itself as a private education provider in Lyon, alongside other denominational institutions in the region. Its location in the historic centre of Lyon gives it particular visibility, as the city is known for the diversity of its public and private schooling options. The institution maintains ties with families, alumni and the local educational community, contributing to the educational and social life of its neighbourhood. Its educational project emphasises the support of pupils throughout their secondary schooling, within a framework combining academic rigour with the human dimension inherited from its religious founding.
The website centresaintmarc.org is the official site of Lycée Saint-Marc and presents institutional, pedagogical and practical information intended for families, pupils and prospective candidates interested in the school.
