The Musée Royal 22e Régiment at the Citadelle has compiled one of the largest military collection in Canada. It covers over 300 years of history, from the New France period until today. The museum showcases the exhibit "Je me souviens" (I remember) which relates to the history of the Citadelle and of the Van Doos, the only francophone infantry regiment in the regular Canadian Forces since 1914. The entrance fee includes a guided tour of the Citadel throughout the year, and in the summer, it also allows for attendance at a musical performance by the Musique en rouge (Regimental Band).
