David Oliete has shot some amazing photos at the Concurs de Castells, a biannual human castle building competition held in Tarragona, Spain.
Oliete's position, along with the colorfully adorned participants make for a unique perspective of the event. The photographs showcase some of the astonishing feats of human determination that goes into building the human towers. Teams have build towers that can reach up to nine and ten stories high during the events.
