There are 2 groups of people that take part in this battle. The first one consists of married men (Els Enfarinats) who gain control over the area and enact absurd laws. They look for people who disobey their orders and fine them. Another group (La Oposicio) tries to fight back. At the end all of the money they gather goes to charity.
Each year 2 rival churches take part in a “war.” They fire a huge number of rockets trying to hit each other’s bell tower. The winner is supposed to be declared by the direct hits, but every time, the churches decide to settle the score the next year.
