A Visit to the Underworld: the Montreal RESO

story and photos by Kayte Deioma

The eastern entrance of the Montreal World Trade Center complex is cut at an angle to preserve the facade of the historic St. James Hotel. Š Kayte DeiomaMany cities around the world have created connecting passageways to allow people to walk between buildings protected from the weather. These range from a few shopping galleries extended from a subway station to miles of underground tunnels or above ground skywalks. Montreal has the distinction of having the longest system of interior passages in the world. Officially christened the RESO, a transliteration of the Frenchréseau, meaning network, the 20 miles (32 km) of underground tunnels and ground-level interior walkways connect hotels, apartment buildings, offices, shopping malls, movie theaters, supermarkets, restaurants, museums and local, regional and national train stations.

Different segments of the Underground City are connected by the metro (subway). Montrealers can leave their apartments and travel across town to work, out to lunch and dinner in different neighborhoods, attend a symphony performance and return home without ever stepping outside. You can do the same thing from your hotel if you stay at any of the nine hotels that are part of the underground system. Even if you don’t have a pressing need to get from here to there, many of the features of this interior world are worth discovering sheerly for their artistic merit or architectural design.

During rush hour, the corridors between office buildings and metro stations are swarming with commuters. Weekends, the high traffic areas are the shopping and entertainment centers. However, in off-peak hours, especially if the weather is fine, foot traffic is sparse. The entire web of passageways is monitored by video cameras to keep the area secure.

Some areas of the RESO are under development or revitalization. They’re still open and functioning as a way to get from point A to point B, but if you happen to enter the system at one of these spots, you’ll wonder what all the fuss is about. Since there are 20 miles of tunnels to choose from, it helps to decide ahead of time what you want to see and map out a plan.

The network will be even more user-friendly if they complete the proposed connection of the Place des Arts and the Bay ( La Baie)department store, which would link the top ends of the U, turning it into an O allowing you to circle around in one direction. As it is, most of the hotels are at the bottom of the U, so to see the sights at the top of both branches, you have to walk outside for a few blocks, take the metro one stop or retrace your steps the long way around.

Place des Arts

The Musée d'Art Contemporain de Montréal  underground entrance. ŠThe Hyatt Regency Hotel is an exception. It is located at Complexe Desjardins at the top of the right branch of the U, which also includes office towers and a shopping mall. Complexe Desjardins is linked to the Place des Arts. This visual and performing arts complex was built in the 1960s and expanded in the 1990s. It includes five performance halls and theMuseum of Contemporary Art, all accessible from an indoor atrium. With 2900 seats, the Salle Wilfrid-Pelletier, is the largest multi-use concert hall in Canada. It is home to the Opera of Montreal, the Montreal Symphony Orchestra and Les Grands Ballets Canadiens de Montréal. The smallest of the concert halls, the Cinquičme salle or fifth hall, never got a proper name. It is easy to locate by the scattering of backwards 5s on the floor leading to the entrance.

Š Kayte DeiomaThe above-ground square surrounded by these arts institutions is the venue for many of the summer arts events like the Montreal Jazz Festival and the Francofolies French music festival. From the indoor Place des Arts, you have a view through glass of sculptures that are in the outdoor courtyard as well as a variety of interior public art and pieces that are a bit of both. Claude Bettinger’s cylinder of curved glass panes reaches above the ceiling to create a unique skylight and a view into the world outside. If you look closely, you can see the reflection of words etched in reverse: L’artiste est celui qui fait voir l’autre côté des choses(The artist is one who makes you see the other side of things).

The Museum of Contemporary Art has an entrance here marked by sleek Complexe Guy-Favreau, Š Kayte Deiomawood and metal signs and panels. If you happen to come by on a winter Monday when the museum is closed, you can get a taste of what’s inside at the museum gift shop La Boutique, which is open seven days.

Below Complexe Desjardins, Complexe Guy-Favreau holds the main offices of the federal government in Montreal. Multistoried windows between the towers allow natural light into the offices rising above the atrium.

Palais des Congrčs

A brown brick corridor and glass skywalk lead to the Place d’Armes metro<The Montreal Palais des Congrčs. Š Kayte Deiomastation, which in turn continues to the Palais des Congrčs (Convention Center) in the International Quarter. The Palais des Congrčs expansion was completed in 2002, followed shortly thereafter by completion of the neighboring Caisse de Dépôt building. The two buildings and the park in between now cover the Autoroute Ville-Marie (720), a 10 lane highway which previously separated Old Montreal from Downtown. Now it’s an easy walk from the International Quarter to the old city, although the interior passages stop just short and you have to go the rest of the way outside.

The Lipstick Forest at the Montreal Palais des Congrčs. Š Kayte DeiomaEach of the four façades of the Palais des Congrčs shows a different view to the world. Its interior features include the Lipstick Forest art installation of mock tree trunks painted lipstick pink and the multicolored windows facing Place Jean-Paul Riopelle that create rainbow squares across the escalators and floor when the light hits just right. This gives the building a very cheerful face from the outside as well.

Š Kayte DeiomaFrom the Palais des Congrčs you can cross underneath the Place Jean-Paul Riopelle toward the Caisse de Dépôt building or toward the Montreal World Trade Center (Centre de commerce mondial). Neither one of these corridors are lined with shops. They each have their own design personality and incorporate features designed to make them feel more open and less claustrophobic.

The Caisse de Dépôt

The Caisse de Depot building is suspended over a ten lane freeway. Š Kayte DeiomaThe Caisse de Dépôt et du Placement (CDP) Capital Centre, which was completed just after the convention center expansion, looks like a rather severe glass rectangle from outside. But the ecologically evolved edifice is actually a suspension bridge over the freeway supporting nine stories of offices. The giant 96-foot white cylindrical steel beams supporting the glass structure crisscross the atrium creating a striking pattern along the length of the building. The CDP is the branch of the Quebec government that manages the state’s pension fund, so that’s really a security desk in the lobby, not just a receptionist. A photo display shows how the building was constructed over the freeway.

World Trade Center

A piece of the Berlin Wall is on display in the atrium of the Montreal World Trade Center. Š Kayte DeiomaThere used to be a gap between the Palais des Congrčs and the Montreal World Trade Center, but the recent additions have connected the two, finishing the bottom of the U. The newest halls incorporate public art as well as installations sponsored by various Montreal art museums.

From the Palais des Congrés, the RESO enters the World Trade Center complex through a peaked glass portal whose angle preserves the back wall of the historic St. James Hotel. You emerge into what used to be Fortification Lane. The old walls to the old city once stood here. The lane is now an indoor passage between two rows of buildings with a glass roof high above. On the right is the InteContinental Hotel. On the left is the St. James Hotel, also known locally as the “movie star hotel.” It is the most expensive hotel in Montreal.

At the far end, the complex incorporates the Nordheimer Building, built in 1888. In front of it is a glassy 18 th century fountain by French architect and sculptor Dieudonné-Barthélemy Guibal.

Promenades Cathédrale

Photos document how a shoping center was constructed under an 1857 cathedral in Montreal. Š Kayte DeiomaAnother interesting spot worth visiting on the underworld web is thePromenades Cathédrale, a shopping mall built below an 1857 Cathedral. It is located toward the top of the left branch of the U near the McGill metro station. In the 1980s, the Christ Church Cathedral didn’t have enough money to do necessary repairs to their tilting tower, so they entered into partnership with a real estate developer to generate income. They created the KPMG Tower, a 35 story sky scraper, which reflects the cathedral, both in its glass façade and in its architectural details. Then they dug out from under the Cathedral and supported it on columns while The rectory of Christ Church Cathedral next to the KMPG Tower built to complement the cathedral.

The rectory was dismantled stone by stone to make way for the tower to be built; then reassembled. It now houses Le Parchemin Restaurant. A photo display documenting the construction progress can be seen in the shopping passages below. A souvenir foldout booklet with photos and descriptions of the process can be obtained for free at the information desk.

ŠBeyond the central segment of the Underground City, other clusters of interconnected passages can be reached by riding the Metro for a few stops. Maps of the RESO can be obtained from most subway stations and hotels or downloaded from the internet. The underground network is also usually indicated on most maps of the downtown area.

There are no regularly scheduled tours of the Underground City, but most of the local tour companies have guides you can hire to narrate your exploration of the RESO at your convenience. Many areas of the RESO, even in the recent additions, are not wheelchair accessible.
