Markham Museum

Markham Museum (originally founded as The Markham District Historical Museum) is a 25-acre (10 ha) open-air museum located in Markham, Ontario, Canada. Opened in 1971 by the Markham District Historical Society with assistance from Markham-Unionville Lions Club and Town of Markham, the Museum used the former Mount Joy School and the surrounding 2 acres.

Over time, heritage structures from the area were moved to the Museum, adding to the 23 surrounding acres of farmland later purchased by the Town of Markham that were slated for redevelopment. In 2011, a new collections storage and exhibition hall opened to the public and in 2019 it was officially named as the John Lunau Centre.

Markham Museum offers a unique open-air experience with over 30 historic buildings, interactive exhibits, public and educational programs, and seasonal events like AppleFest and Scaryfest. The Museum takes pride in fostering community collaboration, offering programs and partnerships that bring people together to celebrate shared heritage and creativity. Regionally and nationally award-winning events and exhibitions mark the Museum's contribution to the community.
