The Chupinazo is the most-anticipated moment of the San Fermin Festival Opening Ceremony. On Thursday, July 6 the square below Town Hall in Pamplona was packed with revellers waiting for the Chupinazo ceremony.

Hundreds of thousands of revellers donned white clothes and red scarves as they gathered in the Town Hall of Pamplona to mark the Chupinazo ceremony.

The crowd cheered wildly as they awaited the pyrotechnic blast that would officially mark the San Fermin festival open. Revellers waved their red scarves in the air.

Participants drank wine during El Chupinazo and stained their white shirts with red wine and sangria.

El Chupinazo marked the official opening of the San Fermin festival that is attended by thousands of people and is famous for its 'encierros'. Six bulls are released at 8:00 a.m. every day to run from their corral to the bullring through the narrow streets of the old town as runners ahead of them try to stay close to the bulls without falling over or being gored.
