Sky was the limit for these incredible competitors taking part in the Human Tower Competition in Spain.
The 26th edition of the tradition ended on Sunday in the city of Tarragona, Catalonia, and saw hundreds of people building human towers or "castells".
The tradition dates back to the 18th century and takes place during festivals in Catalonia, where "colles" or teams compete to build the tallest and most complicated towers.
The structure of the castells varies depending on their complexity. A castell is considered completely successful when it is loaded and unloaded without falling apart.
The highest castell in history was a 10 floor structure with 3 people in each floor.
