Over the past 20 years, Pointe-à-Callière's Port Symphonies have become a true Montréal tradition, filling the air with the joyful sounds of this unusual outdoor concert. Each year, a composer is invited to create a piece coaxing music from the horns of ships overwintering in the Old Port, near the Museum. Train whistles, drums and a variety of other "instruments" join in, delighting crowds of enthusiastic listeners.
