Santa Tecla: La Diada Castellera

Tarragona's Santa Tecla festival is underway and we visited on Sunday 16 September to see the first day of the Castellera - the human castles.

Groups competed to see who could build the highest human towers of different formations. There is always a good, strong base of dozens of the biggest, toughest men, their waists reinforced with an enormously long, black sash that's wound round and round. These men form a giant, circular rugby scrum.

On top of their shoulders climb a group of about 12 slightly smaller men to form the next level. Then up and up they go - each new group shinning up the backs of the others - until we reach six, seven and eight levels. The penultimate level is of delicate teenage girls, wobbling as their ankles are firmly gripped by the men below them.

And finally a tiny child topped with an enormous crash helmet - a boy or a girl of no more than six or seven years old - climbs as fast as they can up the tottering tower to stand and raise their fist at the pinnacle.

Occasionally, they all crash down, but the mass of humanity below seems to cushion the impact.

This was the winning team with their single pillar, five people tall.
