The Montreal Hydrology Museum is located on a small island next to the old town. It looks like a hollow ball and is quite fashionable. The building was transformed from the US Pavilion at the 67th World Expo in Montreal and is supported by a number of triangular steel tubes. In addition to the museum's distinctive appearance, the exhibits are also very distinctive. The exhibits are about the St. Lawrence River and the hydrological characteristics of the earth. I like the earth exhibition hall inside. And there is a multimedia exhibition hall on the first floor, which can be laid flat or on the pillars. It is very leisurely. Due to the snow, the outdoor area in winter is not open. If it is summer, you can also board the outdoor platform and look at the scenery on the other side. If you have time in the evening, you may wish to come over here to see the night scene. There will be various colored lights at night.
