UNESCO intangible world heritage in the Catalan Countries 9/9:
Falles, Pyrenees (Catalonia, Northern Catalonia, and Andorra)
The falles, also known as the Festivities of Fire, are celebrated every year between the summer solstice and the mid July in the Catalan Pyrenees.
When the sun sets, the locals go to the mountain top, where they prepare a bonfire. They eat together and, then, they light the fire and put their flammable wooden sticks in it to set them on fire as well, and they descend to their village carrying the flame. When they reach their village, they are joined by a band of musicians who play the traditional falles march, and in the center of the village all the sticks are put together to make a big bonfire. During that night, they dance around the bonfire. In the morning, people collect embers or ashes to protect their homes or gardens.
Bringing down the flame from the mountains symbolises taking the sun and bringing it down to earth. It’s a remain of the pre-Christian worship of fire, and it’s supposed to bring fertility to the fields and scare away the bad spirits.
(Not to be confused with a different fire festival: the Valencian Falles)
