Read STan Woodcock is not a fan of Lester B. Pearson High School. "I would readily nominate the Lester B. Pearson High School as one of the most ugly bits of construction ever. No 'curbside appeal' whatever! Not only is it named after a politician (pretty disgusting) it looks like it is held together by a series of pipes! The color is something to behold!! Ugly, ugly!"

Reader Diane has some suggestions for improving 17th Avenue S.E. "Yes, the old T&C Motel on 17th Ave SE is old, dilapidated & outdated. If they ever want to spruce up 17th Ave SE this place needs to be torn down!" Courtesy / Google Street View

"Calgary Childrens hospital is ugliest building in town," wrote reader James Jones. "It looks like it was designed by children. Oh yeah, it was. Looking down from Big Four hill, you see a beautiful valley, then get slapped in the face by this glaring, garish and florecent blast of horrid colour. Courtesy / Google Street View

Herald erader Michael has bad memories of his elementary school architecture. "Mayland Heights elementary School --I attended that school for almost a year in the late '60s, and it's uggllyy!" he wrote. "Children, in classrooms on the main floor, could not look directly out of a window! We painted/coloured brown paper rolls to tape up in the hallways to cover the grey concrete. Totally horrid."

Herald reader Annette doesn't like the new Telus Spark building, despite its colourful exterior. "Let’s look at the Academy of Science in Golden Gate Park in San Francisco. Not only it is energy efficient, and innovative, but it’s beautiful like a piece of art of its own," she wrote. "The old Telus World of Science building was ugly enough. I thought the new Telus World of Science is something more unique and artistic. It turn out another architectural disappointment in Calgary. It looks more like a warehouse but a new one. The interior may be wow, but the building shape and exterior style is not wow and not standout. It’s big, all right, but it’s not a piece of art. By the look of it, it’s definitely not a world class. In architecture area, not only efficiency and innovation are necessary, but it also needs to be artistic and pleasing to the eyes. Its architectural design doesn’t stay in people and visitors’ memory. Unfortunately, we have tasteless people who have the authority to signed off this ugly design. " Calgary Herald / Archive

Reader Lee doesn't like the Northhill mall Sears building. "It looks like some kind of factory building from the 50s. It really needs a facelift!" Courtesy / Google Street View

Reader Tammy Ziolkowski has this to say about the C-Train route downtown: "I don't have one particular building - more like a few blocks! Riding the C-train downtown, I am constantly disappointed in the state of 7th avenue - particularly between City Hall and 1st Street stations. Clean it up! It looks like a ghetto!"

Herald reader Quinn K. isn't a fan of One Palliser Square at 125 9th Ave. SE. "It looks like the product of an uninspired, lazy design team that picked a somewhat-brutalist design out of the architectural equivalent of clipart. I bet some rust belt town has this building's twin." Courtesy / Google Street View

It's not in Calgary, but Michael Dawe has found a building to hate in Red Deer. "I think Red Deer's City Hall is a true contender for ugliest public building in Alberta. It has all the architectural ambience of a parkade. P.S. when looking at the photo, concentrate on the building and don't be distracted by the beautiful park in the front. Or better still, do a compare and contrast. " Courtesy / Google Street View

One Calgary Herald reader doesn't like the Calgary airport. "The exterior of YYC is downright drab, with brutalist style concrete dominating the entire front of the building. "The real ugliness, though, is on the inside. It's a bizarre mash-up of small-town bus station meets big-city airport. "The amateur and overdone signage throughout is the worst offender. This place must have more signage per square foot than any other airport in North America (and it's eye-popping yellow, to boot). Compared to major international hub airports, YYC's signage is confusing, often contradictory, and just plain bad. So, in response, YYC just keeps layering more and more signage up all over the place. (A case of more signs being their answer, instead of better signs.) Compare YYC's signage program to YVR's -- which is sleek, understated, even nice to look at. Even better, Vancouver's signage actually works (well) in an airport with global reach and thousands of overseas travellers daily. "Signs aside, some of the worst interior spots in the airport: - The main food court (compare it to The Core, Chinook, or Sunridge -- and you'll think you're in an 80s era discount mall while dining at YYC). (In fairness, the exception to that is the massive southwest window which does provide great views.) - Gate A1: where the domestic commuter flights depart. A depressing little basement followed by long walks through a depressing long tunnel. - All of concourse B/C -- dated, ugly, incredibly cramped -- and designed like one of those old "Habitrail" hamster cages with a complex web of glass wall barriers. (Calgary's adieu to our international visitors is an hour plus in this little hamster cage.) - The parkade exit plaza. Ugly to start with, and now really, really oversigned (and really, really poorly signed, too). You can see each subsequent attempt by YYC's parking folks to get customers to understand how to pay *before* reaching the plaza. Clearly, many YYC customers aren't understan Courtesy / Google Street View

Calgarian Michael Savage doesn't like the new South Calgary Hospital. "The hospital has to be one of the ugliest buildings ever," he wrote. "As I watched it being built, I kept thinking 'I wonder when they're going to cover the insulation?' Then I realized the multi coloured panels ARE the exterior of the building. What happened to Health buildings that looked stately and solid, instead of a psychopaths idea of 'Hell Ride.'" Calgary Herald / Archive

Elveden Centre and Guiness House downtown were Calgary's first skyscrapers, but Herald reader Zach Sonnlietner thinks they are an eyesore. "In my humble opinion the green sided Elvenden Centre and Guiness House built in 1960 and 1964 respectively take the cake," he wrote. "These were the first buildings to immediately come to mind when I read the question." Courtesy / Google Street View

Herald reader Andrew Cunningham suggests the iconic Calgary Tower as one of the city's ugliest buildings. "With the recent construction of the Bow Building, Calgary's 'tower' is dwarfed and looks more and more like a cellular broadcasting tower than an iconic landmark," he wrote. "Its plain concrete lower structure is an industrial eye sore when juxtaposed against the newer and more modern office and condominum buildings popping up all along Calgary's skyline. "The only saving grace for Calgary's almost quarter-century-old 'tower' is when they light the cauldron. But sooner rather than later you won't be able to see it when they do, because all surrounding buildings will be much, much taller." Calgary Herald / Archive

The Calgary Convention Centre draws thousands every year, but Herald reader Bill Skinner isn't a fan of the building. "The new convention centre between 7th and 8th Avenues has a terrible streetscape that is not at all inviting," he wrote. "It seems to be trying to cram too many odd things into a small, boring shoe box." Courtesy / Google Street View

Jamieson Place is rather new, but Calgarian Garry Reimer doesn't think that helps its cause. "The Jamieson Place Tower is ugly," he wrote. "I can't believe that the City would give them a permit to build this thing. What were they thinking???" Calgary Herald / Archive

Several readers said Max Bell Arena is the city's ugliest building, mostly because of the colour scheme plastered on it when the rink was twinned a few years ago. Here's what one reader wrote: "I thought for sure they would peel off those ugly red/orange/yellow tiles and reveal a new modern mirrored glass arena look.... Nope just gonna stick with the ugliness." Courtesy / Google Street View

The landmark buildings of Calgary were not spared by Calgary readers. Reader Cayman Went thinks the home of the Calgary Flames is "the ugliest building in Calgary. Even the name is tacky." Calgary Herald / Archive
