Easily the coolest museum we went to on our trip. This is where the city originally was when it was founded in 1642. After you watch a multimedia presentation (in both French and English) about the history of Montreal and its settlers you start downstairs where you can explore it. The ruins of the old town are basically the basement level of this museum. You will learn about the progress of town through architecture, trade and industry. It was really neat to see all of the old ruins and artifacts. It was very well designed and impressively high tech and interactive. The underground shows the origins of the sewers and walkways and leads you to the the site which used to be the old customs house and square. I'm usually more for art museums, but this one is not to be missed. Nearly four centuries of history for you here. They also had an exhibit on Easter island which was really cool. Also be sure to go all the way to the lookout up top for great views of Old Montreal.
