Every day at 2pm firecrackers rip through the Plaza del Ayuntamiento in an noisy event called la Mascleta. This concert of gunpowder is very popular and involves different neighbourhood groups competing for the most impressive volley, ending with the terremoto, (literally means "earthquake") as hundreds of masclets exploting simultaneously. While this may not be for the frail or faint-fainthearted, you understand how hearted, the Valencians got their valiant name.
