According to tradition, due to the distance between Coquimbo and Santiago, news of the establishment of the First Government Junta on 18 September 1810 arrived two days later. For this reason, 20 September is currently a holiday in the Coquimbo Region and the official closing date of La Pampilla. All these celebrations began to take place annually on 29 July 1823. There are records that indicate that, at the end of the 19th century, horse races were held in this place on 19 and 20 September. According to photographic archives, attendance during the Fiestas Patrias grew in the first decades of the 20th century.
