Pamplona. "Encierro," the Running of the Bulls. Part of the San Fermín festival (July 6-14) it started when bullfighting became a popular pastime, and many bullrings were built. The only way to get the bulls from the corral to the bullring was by running them through the streets to the ring. Eventually, people started running with the bulls. As every year passed, this became more and more popular, and has grown into this extremely important festival.
