Every two years, castellers come together in the city of Tarragona, Spain, to build insanely tall and intricately-formed human towers. The towers are created without any external support, and are marvelous feats of “strength, finesse and balance.”

Watch a short film created by Mike Randolph, showing these brave groups of men, women, and even children participating in this beautiful Catalan tradition.
