The Mysterious Antiquaire of the Chapel of the Expiatory
A curious antique dealer has set up shop at the Chapel of the Expiatory in Paris. A famed collector with a passion for rare, ancient artefacts, he has obviously fallen into the wrong hands — and one of his pieces could prove deadly. Enter Mysteria Ingenium, the renowned agency of extraordinary affairs, which calls on young people and their families to retrieve the enigmatic object. It won’t be easy, because if this dealer hides out at the Chapel of the Expiatory, there’s a very good reason: a relic has caught his eye. The Chapel Expiatoire stands on the site of the old Madeleine cemetery, where many executed during the Revolution were laid to rest, including Louis XVI and Marie-Antoinette. It’s precisely a relic tied to one of these historical figures that interests him. But who owns it now? And what might he trade for it?
Visitors will barter, haggle, and negotiate with a cast of quirky, comical characters. Be a relic hunter for an afternoon and uncover the history of this monument and the historic figures who inhabit it. Think you can swap a potato for diamonds?

The Chapelle expiatoire celebrates the memory of Louis XVI and Marie-Antoinette. At Louis XVIII's request, architect Pierre-François-Léonard Fontaine built aneo-classical monument between 1816 and 1826, with a strong Romantic dimension. It stands on a former cemetery where many of those guillotined during the Revolution, including Louis XVI and Marie-Antoinette, were buried.

A fun and instructive outing for the whole family! Don't delay!
