San Fermin - Pamplona
The celebrations start at noon on 6 July, when the party starts with the setting off the pyrotechnic and continue until midnight, on 14 July, with the singing of the Pobre de Mí. While its most famous event is the encierro, or the running of the bulls, at 8:00 AM from 7 to 14 July, the festival involves many other traditional and folkloric events.
It is known locally as Sanfermines and is held in honour of Saint Fermin, the co-patron of Navarre. Its events were central to the plot of The Sun Also Rises, by Ernest Hemingway, which brought it to the general attention of English-speaking people.
It has become probably the most internationally renowned fiesta in Spain. Over 1,000,000 people come to participate in this festival.
