There are many festivals and festivities in Spain. Some of them are known worldwide, and millions of tourists from all over the world go to Spain annually to experience one of these festivals. One of the most famous is San Fermín, in Pamplona. While its most famous event is the encierro, or the running of the bulls, which happens at 8:00 am from 7 to 14 July, the seven days-long celebration involves many other traditional and folkloric events. The 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.
