From poorly-designed buildings to structural collapses that surprised the globe, the most awful building catastrophes of all time are quite something.

Some caused the lives of countless people while others continue to be standing to this day- yet only just. Below are 30 surprising instances.

2Tacoma Narrows  Bridge

The 1940 opening of the Tacoma Narrows Bridge in Washington was meant to herald a new dawn of civil design, but what was expected to be the world’s 3rd lengthiest suspension bridge rapidly looked to rubble when it fell down after just 4 months!

After much analysis and also examinations, it was figured out that the use of inexpensive girders were responsible. Also when it initially opened, cautioning signs were spotted by vehicle drivers themselves, that contrasted the wobbly suspension to that of a throwing bronco! Adhering to winds of 64 kilometers on the 7th of November, 1940, it soon fell down.
