The Grange Doors Open Mississauga

The Grange

The Grange, located in the historical Robinson-Adamson House, tells its unique story through the many fascinating characters who have owned it over the years. Built for the first Chief Justice of Upper Canada, Sir John Beverley Robinson, the Ontario Regency-style architecture and high-quality craftsmanship supported the importance of this building to the area. Changing hands several times, The Grange was eventually deeded to the City of Mississauga in 1978 and restored. It was designated in 1982 as a significant historical and architectural landmark, and is today home to Heritage Mississauga. During Digital Doors Open, there are many experiences that you can enjoy from the comfort of your own home. Download their heritage-themed comic books and learn more about the history of Mississauga from a unique perspective. Discover local history through their Digital Oral History Projects. Download a self-guided walking tour and explore the many historical areas within the city. Follow on their blog for upcoming online events, question-and-answer sessions with local historians, discussions on local history, and more. And check out their extensive video anthology to learn more about the majestic Credit River, Mississauga’s Indigenous heritage, remembrances of the 1979 Mississauga train derailment, and much more!
