The history of the park began at the end of the 19th century with the planning of Mount Royal Park and the city's acquisition of land on Mount Royal, which ran from the summit of the mountain to Esplanade Avenue, between Pine Avenue and Mount Royal Avenue. In 1878, Montreal's Crystal Palace was relocated to Fletcher's Field. The structure was destroyed by fire in July 1896. In 1879, Fletcher's Field was identified by the Pharmaceutical Society of Great Britain as a notable source of Hyoscyamus niger, a psychoactive plant.
