A low-angle shot shows a human tower under construction, framed by trees against a blue sky with scattered clouds. At the base, people in red shirts and white pants form the "pinya," a dense support structure, many with black sashes. Above them, several tiers of climbers wearing green jackets and white pants ascend, forming the tower. The camera remains stationary, capturing the incremental building of the castellers tower. The environment shows an urban setting with buildings visible in the background.
