The Journées Européennes du Patrimoine 2025, on September 20 and 21, opens the most unexpected doors in Paris! Head for the Hôtel Gouthière, a little-known 18th-century edifice designed by the royal chaser-gilder Pierre Gouthière. Tucked away in the heart of the 2nd arrondissement, this historic pavilion now houses the Hector Berlioz Conservatoire... and it's just waiting for you to reveal its secrets!
