The city’s most colorful building is Palais des Congrès de Montréal. The Convention Centre opened in 1983. After an expansion in 2002, the facility has 200,000 square feet of exhibition space. Since 2012, the most exciting annual event held at Palais des Congrès is the Montreal Comiccon. The three-day program in July draws nearly 60,000 attendants. Le Comiccon de Montréal always features famous names from the comic book industry plus heroes from TV shows, movies and video games. It is fun watching avid fans dressed as their favorite characters as they stroll the streets of Montreal.
