Once upon a time, this place was called Rodoniacum. That’s Rosny-sous-Bois’s ancient name. Let’s journey through the captivating story of Rosny-sous-Bois, a commune nestled in the eastern suburbs of Paris. Only 6.3 miles from the heart of Paris, Rosny-sous-Bois has transformed over centuries.
Rosny-sous-Bois has seen many names. It was Rodoniacum, then Rôny, and later Rosny-sous-Bois-de-Vincennes. Finally, in 1897, it officially became Rosny-sous-Bois. Archaeological digs near Sainte-Geneviève Church reveal a Merovingian village. A papal bull from Pope Alexander III in 1163 mentions Rodoniacum, meaning “the church with the village around it.” Back then, the land belonged to Sainte-Geneviève Abbey. It was a small rural town.
In August 1246, a general emancipation in Île-de-France granted freedom to the inhabitants. The town’s history tells of troubled times, with frequent clashes with the lord abbots. Later, in 1652, the Fronde des Princes foreshadowed the revolution. Rosny-sous-Bois, a priory-cure of the Abbey, had 635 residents in 1788. Farmers made up 64% of the population. The first artisans emerged. They were carpenters, wheelwrights, farriers and framers.
From 1789, the people of Rosny-sous-Bois actively participated in the Revolution. They prudently prepared a list of grievances with the provost of Rosny, Maitre Cottereau. It contained a surprising wish. They wanted the supervision of schools to be secular. This meant not controlled by the clergy. The residents of Rosny paid a heavy price during the wars of the Revolution and Empire. The Fort de Rosny was built from 1840 to 1850 during this era.
From 1850, Rosny-sous-Bois experienced industrial and agricultural expansion. This was thanks to railway development and road improvements. Its proximity to Paris boosted trade. The previously rural population saw the arrival of workers and employees. The war of 1870 left the town in ruins. Industry recovered with the opening of plaster quarries. Many residents worked in Paris.
Between the two world wars, housing estates developed. This pushed back agricultural land. Urbanization accelerated from 1960. Numerous buildings were constructed. These were in Marnaudes, Pré Gentil and Boissière. An industrial zone was created north of the town. There was also a commercial zone and the Garenne activity zone. A new town hall was built in 1964. It sat at the end of the public park bequeathed by Mr. and Mrs. Richard-Gardebled.
Rosny-sous-Bois has become a major city with steady growth. It had 35,823 residents in 1975. By 1982, it was 36,446. In March 1990, the population reached 37,779. By 2022, it was nearly 47,000. In 2024, the estimated population is over 50,000.
Today, Rosny-sous-Bois is known for its commercial activity and extensive residential areas. It is located in eastern Paris, 9 kilometers from the capital. Several highways serve the town. These are the A3, A103 and A86. There are also a dozen bus lines, two RER E stations and three metro line 11 stations. The town is divided into five districts: La Boissière, Coteaux-Beauclair, Centre-ville – Plateau d’Avron – Beauséjour, Marnaudes – Bois-Perrier and Rosny Sud.
Notably, Rosny-sous-Bois has received several awards for its commitment to the environment. These include “Best medium-sized city for biodiversity” in 2017. The town also participates in the “Ville Fleurie” program. This recognizes their environmental efforts. Rosny-sous-Bois also holds the “Terre de Jeux 2024” label. This demonstrates its engagement with the 2024 Paris Olympic Games.
From its ancient roots as Rodoniacum to its modern status, Rosny-sous-Bois embodies a rich history. It also shows a commitment to progress. The town continues to evolve. It balances its heritage with a forward-looking vision.
