Cubiculum Musicae - Châteaudun - La Sainte-Chapelle enchantée

This document presents a comprehensive overview of the "Cubiculum Musicae" exhibition taking place at the Château de Châteaudun from May 15 to November 3, 2025. The innovative installation represents a significant advancement in musical heritage presentation, offering visitors an immersive audiovisual experience centered around historical music. The Cubiculum Musicae installation at Château de Châteaudun, entitled "La Sainte-Chapelle enchantée," is an innovative cultural project developed by CNRS researchers that creates an immersive musical and visual experience designed to revitalize historical musical heritage within architectural spaces. This specific installation focuses on the work of Eloy d'Amerval (c. 1440-c. 1508), a composer who served as canon at Châteaudun, and his masterpiece "Missa Dixerunt discipuli." The exhibition is structured as a three-part experience: an evocative audiovisual projection in the chapel sacristy featuring the Odhecaton ensemble performing d'Amerval's mass, contextual information presented through informational displays about medieval Sainte-Chapelles, and an interactive touchscreen allowing detailed exploration of the musical composition. Developed through rigorous musicological research, the project represents a novel approach to making historical music accessible to contemporary audiences while highlighting the musical heritage of Sainte-Chapelles. The initiative also features a dual installation at Paris Gare d'Austerlitz, creating a cultural connection between a major transit hub and the historical site, aiming to redistribute tourist flows and enhance cultural engagement. This project exemplifies how advanced research in musicology can create concrete applications that make previously inaccessible musical heritage available to broader audiences through contemporary technology.
