For Heritage Days, the medieval town of Château-Landon invites you to join them on 19 and 20 September 2026 for an exceptional tour through its monuments, including the lesser-known ones, in the heart of Seine-et-Marne.
Château-Landon sets July 13, 2026 as the date for a summer National Day celebration in Seine-et-Marne. In the steep, rugged setting of this Gâtinais town, the festivities unfold as a blend of heritage, reunions and a full midsummer atmosphere.
Extracted in Seine-et-Marne, the Château-Landon stone has helped build or restore several of Paris’s major monuments, from the Arc de Triomphe to the Sacré-Cœur. A geological heritage of Île-de-France, quiet but clearly visible throughout the capital.
Perched atop its rocky outcrop, Château-Landon is a charming medieval town in Île-de-France. Its terraced gardens, narrow cobbled streets, and historic landmarks tell a centuries-old story, blending legendary tales with well-preserved heritage.
