San Fermín a fireworks display at the city hall. This closing ceremony tradition started out in the 1920s. The running of the bulls (In Spanish "encierro or los toros de san Fermin") involves hundreds of people running in front of six bulls and another six steers down an 825-meter (0.51 mile) stretch of narrow streets of a section of the old town of Pamplona. The run ends in the Pamplona's bullring taking a mean time of around 3 minutes where the bulls would be held until the afternoon's bullfight when they would be killed. Bullruns are held between July 7 and 14
Running of the bulls wooden fences is erected to direct the bulls along the route and to block off side streets. A double wooden fence is used in those areas where there is enough space, while in other parts the buildings of the street act as barriers. The gaps in the barricades are wide enough for a human to slip through but narrow enough to block a bull. The fence is composed of approximately three thousand separate pieces of wood. Some parts of the fence remain in place for the duration of the fiesta, while others are placed and removed each morning. Spectators can
