 Constructed in 1889 by the Northern Pacific and Manitoba Railway Company, the building originally included a machine and blacksmith shop, engine house and a ten-stall roundhouse and turntable.Designed by John Woodman, it was typical example of a late nineteenth-century industrial building and was formally recognized as a Provincial Heritage Site on 22 March 1995.Following a $10M capital campaign in 2010 and 2011 which included the development of 12 new permanent galleries, a renovated Arts & Exhibition Centre, and the Buhler Welcome Centre addition, the Children's Museum reopened to the public in celebration of its 25th birthday on 4 June 2011.
