I’ve always been a fan of “how things work” type videos, but this animation of how 14th Century bridges were constructed is amazing. The way they did everything in stages and built something we can still enjoy today fascinates me. The video in question shows how the 516 m. (1,693 ft) of the historic Charles Bridge in Prague, Czech Republic, came to be in 1357.
