Near the Olympic Park and the botanical garden, the Dufresne-Nincheri Museum (Musée Dufresne-Nincheri) is located in the Château Dufresne. A visit provides a glimpse of post–Gilded Age life, Montréal-style. The 1,860-square-meter (20,000-square-foot) Beaux-Arts mansion was constructed from 1915 to 1918 for the Dufresne brothers, two successful French Canadian businessmen. The house, modeled on the Petit Trianon, was divided in two, with each brother having a separate household. In addition to offering the opportunity to view the opulent home, the museum has a collection of artifacts connected to famous French historical figures and pieces from the workshop of Guido Nincheri, an Italian immigrant to Canada who established the country's oldest stained-glass studio.
