Montreal Underground City: What Lies Beneath Downtown Montreal

Photos of the Largest Underground City in the World

I'll be the first to admit the Montreal underground city's status as a must-see attraction is blown a bit out of proportion.

From a tourist-who's-seen-it-all perspective, it's a bunch of malls connected together. And from many a local's point of view, the largest underground city in the world is but a practicality. Hundreds of thousands of daily commuters seek refuge from the winter cold as they trek to and from work in its 33 kilometres of climate-controlled tunnels, corridors, hotels, and shopping centres.

But if you ask me, the underground has its charm. Parts of the network are stunning, a joy to walk through. If you can find them.

Ironically, those same stretches are rarely, if ever seen in guidebooks or on the Internet, possibly because said corridors are mapped out like a labyrinth. As a result, many tourists, relocated newbies and even Montreal natives ignore these places exist. So as your humble guide, I...MORE thought it would be fun to show you the underground city's unsung nooks and crannies, especially since it's not always easy to find them. 

There isn'y even a clear map of the underground city.

This photo here was taken inside the Centre de Commerce Mondial, otherwise known as the Montreal Trade Centre, during Art Souterrain, an annual event that turns Montreal's underground city into a sprawling art exhibit.

Select Montreal hotels are directly connected to the underground city allowing guests to travel from Point A to Point B without setting foot outside, a boon on cold winter nights.

This section of Montreal's underground city is in Place Bonaventure, a building used primarily as an office building and convention centre completed in time for Expo '67 which in its heyday, ​was the largest concrete building in the world.

Place des Arts, Montreal's largest performance arts complex, is connected to the underground city.

The projections as seen above in its main corridor were captured on November 23, 2016. The project is called "Le public" and represents the emotional reactions of the audience as perceived by stage artists. It's a Baillat Cardell & Fils creation in collaboration with the illustrators Capucine Labarthe and Lino.

Located across the street from Place des Arts in the Quartier des Spectacles, Complexe Desjardins is one of the Montreal underground city's connector buildings. It's a mall, an events centre, an office building, and a hotel wrapped in one.

The most intriguing sections of Montreal's underground city are its corridors, some of which look like they're straight out of a sci-fi flick. 

Montreal convention centre Palais des congrès is a major part of the underground city, connecting pedestrians to Chinatown, Old Montreal, and the downtown core. Several hotels surround the convention centre.

Select parts of Montreal's subway network are integrated into the underground city network, notably Bonaventure, McGill, Square-Victoria, and Place d'Armes Metro stations.
