A popular tourist attraction is to climb Mount Royal (Mount Royal = Montreal = Get it?)

A really neat Garden and Insect Museum is near the Olympic Complex.

Notre Dame is one of the most beautiful churches in North America.

Doesn't Olympic Stadium kind of look like a toilet bowl?

A great museum ... Montreal Underground. I'm always interested to see the underground living conditions from years past. The museum acts as an archaeology site. Similar sites can be found all over the world, the deeper you go, the older you go, even to Native American civilizations.
