Built in 1918 in the Beaux-Arts style, the Château Dufresne is a former mansion owned by the Dufresne brothers. The building houses the museum dedicated to the history and heritage of Montréal's east end. Its permanent exhibition has been completely revamped. The mansion’s interior, painted by artist Guido Nincheri (1885-1973) in the 1920s, and its furnishings reflect the bourgeoisie tastes of the era. Visitors can also tour Nincheri’s studio. The artist helped to decorate, with murals and stained-glass windows, more than 200 buildings across 116 locations in Canada and the United States.
