Northeast of the capital, Seine-Saint-Denis is youthful, multicultural, and fast-changing. Saint-Denis boasts France’s royal necropolis and the Stade de France, while Montreuil buzzes with artists, and Le Raincy shows off Art Nouveau elegance. Grand-Paris projects and 2024 Olympic venues are transforming the area. Housing mixes 19th-century terraces, modern eco-developments, and loft conversions—attracting first-time buyers and creatives.
