We were here for about 2 hours and could have stayed longer. We found the exhibits to be very interesting.
There were 3 distinct exhibit areas. First was the Old Montreal portion, which started with a short film and was followed by a guided walk through some of the features that extend underground to the other side of the street--small dioramas about how the city looked during various time periods, an old pillar from a building that once stood here, the remnants of a river that once flowed where the street now is, the old foundation from the city's early years, etc. My kids (ages 10 and 13) were fascinated. They really liked the interactive videos and checking out the nooks and crannies in the old foundation area.
Once you cross under the street, there is an entirely separate "modern" exhibit area in the floors above the old foundation. It was hard to find. The content, however, was great. One of the best parts was called "Love Stories" and involved different people talking about their connections to Montreal and to their spouses/partners. I wish that we had allocated more time to spend watching the videos and listening to the stories. Such richness.
The final exhibit area had a rotating special exhibit. During our visit, there was a wonderful collection of Samurai armor with explanations regarding the history and cultural significance of the samurai and their traditions.
I am giving the museum 5 stars for the great content. However, the layout was extremely confusing. I think most people miss the 2nd portion of the museum entirely because there is a lack of signage that it even exists (we were the only ones up there, although the rest of the museum was very crowded). Also, in trying to find the front entrance after leaving the underground area, we inadvertently ended up coming out of a side door into the back of the Samurai exhibit, where a worker rushed over to tell us that we should not have come that way. (We had no idea1) Also, if you don't take the main elevator to the special exhibit, you have to go up and down stairs that are not clearly marked and feel as if they are not intended for public use.
Better planning and signs are needed throughout! Otherwise, excellent museum.
