The bull is undeniably one of the main protagonists of the Sanfermines. These fighting bulls and the mozos (young men) come together at 8 a.m. every morning of the fiesta for the Encierro, the best-known event of Pamplona's fiesta. The bullfight takes place in the evening, a spectacle in which the contrast between the silence of the spectators in the seats in the sombra (shade) contrasts with the noise and rollicking of the peñas (social clubs) in the sol (sun) area. Just after nightfall the Encierrillo takes place. In a surprising atmosphere of quietness and without runners, the bulls are sent from the 'corrales del gas' to the corral in calle Santo Domingo, the starting point of the bull run.
