Abbaye royale de Royaumont, Abbaye de Royaumont - 95270 Asnières-sur-Oise
From 16 to 18 April 2027
A unique European event to discover castles, abbeys and historic sites in a new light through night-time tours, illuminations and unusual visits
On April 16, 17, and 18, 2027, the Night of Monuments opens the doors to the most beautiful architectural treasures as night falls. This event, now a must-see, transforms castles, abbeys, and fortresses into venues for immersive experiences. In Greater Paris, two exceptional sites stand out: the Château de Grosbois, which unveils its imperial salons and historic stables, and the Abbaye de Royaumont, where the architecture comes to life during nighttime strolls. Each monument offers a customized program: torchlight tours, live performances, and even exclusive access to areas that are usually off-limits. It’s a rare opportunity to raise awareness among all generations about heritage preservation through emotion and the extraordinary.
