VIDEO: These Are the Biggest Fails in Architecture History

We all enjoy going on vacation and marveling at extraordinary architecture of foreign cities.

But while there are a lot of wonderful buildings, there are some that are just ugly and others that are actually dangerous.

Some architects take it too far when trying to make something interesting and beautiful and end up forgetting important things.

According to list25.com, the right architectural designs can be a breath-taking sight and a stunning human achievement.

But, when architects get it wrong, it’s like a ketchup stain on a white shirt.

From ugly hotels to poorly designed bridges, the worst architecture in the world can be devastating to the eye and, on rare occasions, dangerous to the public.

Here are the 25 Biggest Architecture Fails You’ll Ever See.

And oldie but a goodie, the Leaning Tower of Pisa feels like the right way to start off this list. While architects started building it in 1173, it didn’t get completed until the 1300’s.

The soft, marshy land is the main reason it leans. Apparently, looking over the foundation before construction wasn’t on their checklist.

Oh, look, it’s a standard, boring skyscraper that looks like all the others.

Honestly, the real issue with the Standard Oil Building, now Aon Center, was back in 1974 when the geniuses decided to slap expensive marble along the sides of the building.

Sure enough, the marble cracked and a big piece came off, falling on top of the building next to it. Needless to say, they had to do some renovations.

Acting as a catch-all auditorium for Brooklyn, New York, Barclays Center is a rusty, oblong building with a very big hole in the roof of the entryway.

With the big blue title displayed prominently on the front, it looks more like a hospital with an identity crisis.

Located in London, the Secret Intelligence Service Building is home to MI6 and fictional character James Bond.

For a building with the word “secret” in it, this one is failing miserably at its job.

It’s overpowering presence might as well have a billboard that reads, “Big Brother is watching.”

The Žižkov Television Tower looks like a spaceship landed in the middle of a very old city, creating a skyline that’ll make most tourists do a double take.

That’s not even the weirdest part about it. Sculptures of naked babies look like they’re crawling up and down it.

The John Hancock Tower in Boston is their tallest building and also their most deadly.

While it was being constructed, the 500-pound windows installed would suddenly pop out, potentially falling on the bystanders below.

It continued to happen, and they finally realized the window design was wrong and had to replace all 10, 334 window panes.

Las Vegas can get pretty hot at times but people lying by the pool rarely expect their hair to singe or their cups to melt.

This is exactly what happened at the Vdara Hotel, where guests complained that its windows magnify the sun’s heat, creating a “death ray.”
