Île de la Cité

Île de la Cité is the historic heart of Paris located on a natural island in the River Seine and is one of the city’s oldest settled areas. It contains major medieval and state buildings including churches, the former royal palace and judicial institutions.

The island’s principal visitor attractions include the cathedral of Notre-Dame, the royal chapel of Sainte-Chapelle with its medieval stained glass, and the Conciergerie, a former palace and prison. Small squares, quays and gardens around the island provide riverfront views and access to river transport.

The island developed as the administrative and religious centre of medieval Paris, with royal and ecclesiastical functions concentrated there for centuries. Many of the island’s buildings retain medieval and early-modern fabric, though individual structures have undergone restorations and changes over time.

Île de la Cité sits in the centre of Paris within the 4th arrondissement and is connected to the rest of the city by several bridges, lying adjacent to the Left Bank and the Marais district.

• Sainte-Chapelle windows: Sainte-Chapelle contains one of the finest collections of 13th-century stained glass in Europe and is a short walk from the cathedral interior.
• Notre-Dame restoration: Notre-Dame suffered major fire damage in 2019 and is the subject of a long-term restoration project; parts of the complex remain closed to the public during works.
