Fun fact: Charles bridge (depicted in the video) was damaged during a flood in 1890. With the water level risen, broken down rafts were beating its arches and two of them fell apart, along with three pillars that were undermined by the water. During the reconstruction of the pillars, they decided to make them hollow (to cut on the weight) and you can actually go inside! It's not open to the public but there's a video…
Normally I do not pay attention to ads but was curious to know - what was that Santa selling! And I can't speak a word of Czech. 1:26' into the video - Is that guy praying? Read there are statues of Saints on the bridge. Found an image of 1872 flood - https://en.wikipedia.org/wiki/Charles_Bridge#/media/File:FFr...
