The Ecole des arts joailliers, located in the heart of the magnificent Hôtel de Mercy-Argenteau, is opening its doors to the public with a host of events for its first participation in the Journées du Patrimoine, on September 20 and 21, 2025.

The Journées du Patrimoine 2025 (Heritage Days 2025 ) are back, giving you the chance to discover emblematic places that are often closed to the public! Churches, historic monuments, castles and other spots that sometimes open exceptionally are waiting to reveal all their secrets to you on September 20 and 21. Launched in 1984, these days are an opportunity for the general public to discover cultural heritage through guided tours and free activities.

In Paris, many of the city's private mansions hide behind beautiful facades. Located at 16 bis boulevard Montmartre, the Hôtel de Mercy-Argenteau provides a prestigious new setting for L'École des Arts Joailliers. What could be more beautiful than this listed hotel to host the school's free exhibitions? A hidden treasure, founded with the support of Van Cleef & Arpels to promote jewelry culture.

Throughout the year, visitors can discover its rich history and neoclassical architecture at jewelry exhibitions in the reception rooms, adorned with gilded woodwork and Corinthian porticos. A spacious library and a unique bookshop, L'Escarboucle, complete the space available to visitors. Don't forget, reservations are essential!
