Goldmines of heritage information

Montréal heritage databases contain hundreds of files on buildings and areas of heritage interest. They present the history and architectural or urban characteristics of these sites using brief texts, photos, illustrations and other old and contemporary documents.

Heritage buildings

This history and heritage outreach resource presents data from three inventories developed between 1998 and 2020: the Old Montréal site, the city’s comprehensive inventory of built heritage, and the inventory of municipal historic builldings.

It also houses complementary files on numerous subjects, including on heritage areas, noteworthy figures, as well as historical periods and events.

Additional data on buildings, including on architectural features, are also accessible via the city’s open-data platform.
