It is hard to miss. If you are driving into downtown Calgary from the east, the skyline hits you all at once, but one building tends to hog the spotlight. It’s a massive, crescent-shaped glass giant that looks like it’s trying to scoop up the Rocky Mountains. Most people just call it the Bow building in Calgary, and honestly, even after being part of the skyline for over a decade, it still feels a bit like it landed from the future.
But here’s the thing. It isn't just an office. It’s a statement about a city that was trying to outgrow its "Cowtown" reputation.
When Encana (now Ovintiv) and Cenovus decided to build this thing, Calgary was riding a massive energy wave. It was 2007. The money was flowing. They wanted something that didn’t look like the beige, boxy towers that dominate 5th Avenue. They hired Norman Foster—Lord Foster, if you’re being fancy—of Foster + Partners. If you don't know the name, he’s the guy behind the "Gherkin" in London and the Apple Park "spaceship" in Cupertino. Bringing a "Starchitect" to Calgary was a huge deal. It was the city saying, "We’ve arrived."
The Bow building in Calgary and the geometry of wind
Have you ever walked around a skyscraper and felt like you were in a wind tunnel? That’s because most buildings are terrible at handling the aerodynamics of a flat prairie city. The Bow is different. Its shape is not just for aesthetics; it is a calculated response to the environment.
The convex side of the building faces the prevailing winds. By curving the glass, the architects effectively deflected the wind loads, which allowed them to use a much lighter steel frame than a traditional rectangular building would require. It’s basically a massive glass sail. Because the structure is so efficient, they saved a staggering amount of steel—thousands of tonnes, actually.

Inside that curve, something cool happens. The "atrium" spaces act as a massive solar collector. Calgary is famously sunny, even when it’s $-30^\circ\text{C}$ outside. The building traps that heat. It’s like a giant greenhouse for oil executives. They created these "sky gardens" every few floors where employees can hang out, and because of the south-facing glass, those plants actually survive a Canadian winter. It was a massive shift in how Calgary thought about workplace wellness before that was even a buzzword.
That giant head in the plaza
You can’t talk about the Bow without mentioning Wonderland. You know the one—the 12-metre tall wire-mesh head sitting in the south plaza. It was created by Spanish sculptor Jaume Plensa.
Honestly? People were confused at first. It’s a young girl’s head, and you can actually walk inside of it. Some folks call it the "Giant Head," others just use it as a landmark to meet their Tinder dates. But Plensa’s idea was that the architecture of the body mirrors the architecture of the city. It’s become arguably the most photographed spot in the entire downtown core. If you go there at night, the way the light catches the white mesh against the dark glass of the tower is genuinely stunning. It grounds the massive scale of the skyscraper into something human and, well, weird.
A construction project that almost broke
It wasn't all smooth sailing. Not even close.
The 2008 financial crisis hit right in the middle of construction. There was a point where people genuinely thought the Bow building in Calgary would end up as a half-finished skeleton of steel. Encana ended up selling the building to H&R REIT to free up cash, then leasing it back. It was a massive financial pivot that saved the project.

When it finally opened in 2012, it was the tallest building in Canada outside of Toronto. It held that title until Brookfield Place East snuck past it a few years later. But even at 236 metres (774 feet), the Bow feels bigger because of its footprint. It occupies two full city blocks. To make that work without ruining traffic, they had to build over 6th Avenue, creating a massive internal connection that keeps the city moving underneath.
The Diagrid: More than just pretty diamonds
Look closely at the facade. You see those diagonal steel beams? That’s a "diagrid" system.
Usually, buildings rely on vertical columns. The Bow uses these triangles to distribute the weight. It’s incredibly strong. Because the triangles handle the heavy lifting, the interior floors are almost entirely open. No annoying pillars blocking your view of the mountains. If you’re lucky enough to have an office on the 50th floor, you have a 270-degree view that is basically unmatched in Western Canada.
It’s also surprisingly sustainable for a building of its size. At the time, it was a leader in LEED Gold certification. They used recycled content in the steel and high-efficiency glass to keep the heating bills from being astronomical. In a city where the temperature swings $40$ degrees in a single week, that’s a feat of engineering.
Why the Bow matters for Calgary’s future
The energy industry has changed since 2012. The massive headquarters of the past are being reimagined. For a while, there was a lot of "empty" space in the Bow as companies downsized or moved. But the building is adapting.
It’s no longer just a temple to oil and gas. It’s a symbol of Calgary’s resilience. We’ve seen tech companies moving into the core, and the Bow remains the "crown jewel" of the rental market. If you want to show a client you’re serious, you get a desk in the Bow.
It also changed how the city interacts with the street. Before the Bow, the "East Village" area was... let’s just say it was struggling. The Bow acted as an anchor. It pulled the center of gravity of downtown further east, paving the way for the new Central Library and the revitalization of the entire district.
What to do when you visit
If you’re just visiting, don’t just look at it from the outside.
- Enter through the +15: Calgary has the world’s most extensive skywalk system. You can walk right into the Bow from the surrounding buildings without ever touching the snow.
- The Sky Gardens: While most of the building is private, there are often public events or ways to see the lower atrium levels. The scale of the glass looking up is dizzying.
- The Night View: Go to the Centre Street Bridge at dusk. The way the Bow reflects the sunset is the definitive Calgary photo op.
- The "Inner" Head: Walk inside the Wonderland sculpture. The acoustics change, and looking up through the mesh at the tower above gives you a totally different perspective on the height.
The Bow building in Calgary isn't just a workplace. It’s a weather-shield, a piece of art, and a reminder of a boom-town era that shaped the modern city. Even if you aren't into architecture, you have to respect the sheer guts it took to build something this curved in a world of straight lines.
Actionable Insights for Your Visit:
- Best Photo Spot: Head to the corner of 6th Ave and 1st St SE for the classic "Wonderland" shot with the tower looming behind.
- Timing: Visit during the "Golden Hour" (just before sunset). The glass is designed to reflect the prairie sky, and it turns a deep copper color that is incredible for photography.
- Accessibility: The plaza is fully public and accessible 24/7. If you want to go inside, aim for business hours (8 AM - 5 PM) to access the publicly reachable lobby areas and the +15 connections.
- Nearby Stops: After seeing the Bow, walk two blocks east to the Calgary Central Library. The architectural contrast between the Bow’s steel and the Library’s wood/geometric glass is a masterclass in modern design.
The Bow stands as a bridge between the old Calgary and the new, proving that even in the heart of the prairies, we can build something that competes on a global stage. It remains a mandatory stop for anyone trying to understand the pulse of this city.
