Charles-Édouard Jeanneret-Gris, a Swiss-born architect who later became known as **Le Corbusier**, was born into a Protestant family in La-Chaux-de-Fonds, Switzerland. He is best known for his contributions to modern architecture and urban planning. One of his notable works is the Cité de Refuge, a housing complex he designed in Paris in 1933 for the Salvation Army. This project came three years after he was naturalized as a French citizen, according to Mon Calendrier protestant. **Le Corbusier** was one of the pioneers of modern architecture, known for his innovative ideas about how buildings and cities should be designed. One of his most influential concepts was the "unité d'habitation," a type of housing that aimed to provide all necessary facilities within a single building. This idea was a response to the housing shortages and social challenges after World War II. Five versions of the "unité d'habitation de grandeur conforme," as **Le Corbusier** called it, were built after the war in different cities: Marseille, Briey-en-Forêt (Meurthe-et-Moselle), Rezé (Loire-Atlantique), Firminy (Loire), and Berlin. These buildings include communal spaces like daycares, laundries, swimming pools, schools, and shops, reflecting **Le Corbusier**'s vision of self-contained, functional living environments. The architectural legacy of **Le Corbusier** is vast and significant. In 2016, 17 of his works were collectively classified as a UNESCO World Heritage Site under the designation "Forte," with 10 of these sites located in France. This recognition highlights the global influence of his designs. In 2019, a European cultural route called "Destinations Le Corbusier: architectural walks" was established, allowing visitors to explore and appreciate his architectural contributions across Europe.
