Stewart museum, History museum in Montreal, Canada

The Stewart Museum occupied the British fortified depot on Île Sainte-Hélène, in Montreal's Parc Jean-Drapeau. Its permanent exhibition "Histoires et Mémoires", opened in June 2011, presented over 500 objects across five centuries, from Indigenous presence at the European arrival through the French and British periods. A four-storey glass tower by architects André Lavoie and Éric Gauthier served as the entrance, with an elevator and a rooftop lookout over the city, the Jacques-Cartier Bridge and the river.

David M. Stewart founded the museum on 2 July 1955 in the blockhouse of the Fort de l'Île Sainte-Hélène; 32,000 visitors came in its first summer. Renovations begun in 2008 ran two and a half years and cost 7 million dollars, adding a four-storey glass entrance tower by architects André Lavoie and Éric Gauthier; the museum reopened on 29 June 2011. It merged with the McCord Museum in 2013 and closed permanently in February 2021, its collections transferred to the McCord Stewart Museum.

The permanent exhibition "Histoires et Mémoires", open since June 2011, led visitors through five centuries in more than 500 objects, from the Indigenous presence at the Europeans' arrival to the French period of New France and the British period, including relations with the American people. Its centrepiece was the interactive model of Ville-Marie, explained by a bilingual audio guide.

The museum closed permanently in February 2021, so the blockhouse in the Sainte-Hélène Island fort can no longer be visited. Its roughly 27,000 artefacts went to the McCord Stewart Museum, which has carried the Stewart name since 31 August 2022. Look for the collection there rather than at Parc Jean-Drapeau.

The collections were digitized and made available through a new online platform starting in fall 2021. This shift allowed the museum to continue its educational mission even though its physical location no longer exists.
