Late-afternoon sunlight streams through tinted panes of glass in Montreal's Palais de Congrés casting colorful, elongated shadows on the gray stone floor of the building's lobby.
For a short time each afternoon, sunlight hits the building at the just right angle to pass through the colored-glass facade and back out through a transparent glass wall on another side of the building, creating a momentary spectacle of tinted shadows on an adjacent street.
Alternating facades of transparent and tinted glass envelope the Palais de Congrés. Rue de Bleury, Montreal, Quebec.
