Heritage Days 2025 at the Lycée Carnot

Every year, the Journées du Patrimoine (Heritage Days) are held on a weekend in September: in 2025, the dates are September 20 and 21. This national and European event opens up historic sites, often closed, for free visits, workshops and exhibitions. Discovery and heritage are at the heart of these days: it's the perfect opportunity to (re)discover Paris from a cultural and festive angle.

The Lycée Carnot, in the 17ᵉ arrondissement of Paris, has a fascinating history. Built in 1869 as theÉcole Monge, it was renamed "Carnot" in 1895 as a tribute to President Sadi Carnot, assassinated the previous year. Designed by architect Hector Degeorge, with a metal structure by Gustave Eiffel, the building now accommodates nearly 2,400 students, from primary to preparatory classes. Its artistic heritage is rich: a war memorial designed by François Cogné, a historic chapel, old laboratories and a gymnasium on stilts bear witness to over a century of architectural evolution.
