I can’t say it any better than the creator of this video, Mike Randolph, so I’ll simply quote him below:
In the city of Tarragona, Spain, Castellers gather every two years to see who can build the highest, most intricate human castles. This Catalan tradition requires astonishing strength, finesse, and balance. Not to mention courage.
There are definitely more than a few “Holy Shit!” moments in this video, so be prepared for heavy doses of awe, terror, and victory in equal parts.
