Behind the scenes at Montréal’s city hall

“Behind the scenes at Montréal’s city hall” explores an iconic civic building through two formats: a guided tour or an investigation game introduced in 2026. The one‑hour tour covers the ground floor and first level, including select ceremonial rooms usually closed to the public. “Mystère à l’hôtel de ville: À la recherche des clés perdues” offers a 90‑minute interactive experience available Wednesday to Friday in French. Schedules may vary; activities are cancelled on public holidays and during council sittings.
