Every year on January 17,the people of San Bartolome de Pinares celebrate St. Anthony by riding their horses, donkeys and mules through piles of burning tree branches.

The unique tradition of leaping over and through flames dates back 500 years, but the men and women of San Bartolome de Pinares still celebrate it religiously. They gather all the branches they find in the days leading up to the festivities, and when dusk falls on the eve of Saint Anthony’s, they light them ablaze. Riders lead their mounts through the burning piles of the village, accompanied by sounds of drums and Spanish bagpipes.
