It looms on the edge of downtown a stone's throw from the Calgary Tower, a splash of colour amid aging buildings, railway tracks, parkades and a steady stream of traffic.
It's billed as the world's tallest mural, painted by one of the globe's top graffiti artists, and is part of a project to turn an austere area of downtown into an expansive open-air urban art gallery.
"The brutalism and dystopian look of this area with the giant parkades and the spiral ramps and stuff — it feels like Gotham. So turning this wall from concrete nothing to this is really fun," said Peter Oliver, president of the Beltline Urban Murals Project, or BUMP.
The mural is an abstract painting in various shades of orange, black, grey, blue, white and yellow and is the creation of DAIM, an internationally renowned German artist. DAIM, whose real name is Mirko Reisser, has been creating public artworks for more than 30 years.
"DAIM's work is rooted in graffiti art. It's abstract and he was actually the very first graffiti artist to start exploring three-dimensional works. So his work kind of obeys the laws of light and shadow but defies the laws of gravity," Oliver said.
"I think his work really marries well with the brutalism of this building and it's just a massive flat wall of concrete. It's the very first prefabricated concrete building in Calgary, built in 1980."
The mural is 95 metres high, making it the tallest mural in the world "by a long shot," said Oliver.
He said most cities don't have giant concrete walls available, with the majority being glass, steel or aluminum. So this was a perfect marriage.
DAIM, who was assisted by three local artists, spent over three weeks painting and went through more than 500 cans of spray paint after a base coat was added to the bare concrete. It is to be a permanent addition to the area and, as of last week, was awaiting a coat of UV sealant to make it complete.
Facing toward the east, it can be seen from a long way away.
"If you've got the window seat on the airplane, you can see it on the approach into the airport," Oliver said.
"I think what we're really doing with BUMP is re-architecting the identity of this city."
The project will be unveiling about 60 new murals during its annual festival, which runs from Aug. 1 to 28. Before that, the new art work can be viewed by visitors at the annual Calgary Stampede, which begins this week.
"If you're coming down, I'd check this out over the parade any day," Oliver said with a chuckle.
