Rennes — Brittany, France

Rennes (French: [ʁɛn] ) is a city in the east of Brittany in Northwestern France at the confluence of the rivers Ille and Vilaine. Rennes is the prefecture of the Brittany region and Ille-et-Vilaine department. In 2023, the city had a population of 230,890 inhabitants, while the larger metropolitan area is the 10th most populated in France with a population of 789,516.

The inhabitants of Rennes are called Rennais (masculine) and Rennaises (feminine) in French.

Rennes's history goes back more than 2,000 years to a time when it was a small Gallican village named "Condate." Together with Vannes and Nantes, it was one of the major cities of the ancient Duchy of Brittany.

From the early sixteenth century until the French Revolution, Rennes was a parliamentary, administrative and garrison city of the historic province of Brittany in the Kingdom of France, as evidenced by its 17th-century Parliament's Palace. Rennes played an important role in the Stamped Paper Revolt (Revolt of the papier timbré) in 1675.
