European Museum Night 2026

On Saturday, May 23, 2026, the Hôtel Gaillard will open its monumental doors at dusk. This architectural jewel, usually dedicated to the workings of finance, comes to life during an exceptional evening event. The evening begins under the shade of the Monceau Park for a guided walk that reveals the secrets of the neighboring historic residences. Once the moat of this Renaissance-style building has been crossed, passionate students take over. Their short, dynamic interventions shed light on the history of this remarkable heritage, transforming the visit into a lively exchange. Between the state rooms and sculpted details, this nocturnal stroll offers a fresh perspective on a prestigious urban environment. It’s an opportunity to contemplate economics from a cultural and human angle, away from the numbers, in the heart of a fairytale setting.
