Montréal City Hall
Montréal City Hall has a more turbulent history than its peaceful façade suggests. The building went up between 1872 and 1878, and survived a severe fire in 1922. And it was from this balcony that French President General de Gaulle uttered his famous "Vive le Québec libre!" during a state visit in 1967. (Listen closely and you can still hear the crowds roaring.)
When you're there, take a moment to admire the Hall of Honour or, better yet, sign up for a guided tour. All are welcome.
