La tamborrada is the event which every January 20th the city celebrates the day of San Sebastian.
The origins go back to the year of 1597, when an epidemic plague stroke the city. Many inhabitants went to the Church of San Sebastian el Antiguo praying for their protection. The epidemic finished and in gratitude to the Saint the neighbors made a vow to take San Sebastian as patron of the city and to celebrate annually the event.
Each tamborrada must be sponsored by a charity, cultural, sporting, gastronomic or recreational society of the city. Each Tamborrada must be uniformed. Its components are usually divided, having at least one company of drums and another one of barrels. It is also mandatory that the Tamborrada parade is accompanied by a music band.
