On this day a procession was held in the early 19th century from the Santa Maria Church in the Old Part to the San Sebastián Church in the district of Antiguo, while later limited on the grounds of weather conditions to the in-wall area. The event finished with a popular dancing accompanied on the military band's flutes and drums. In addition, every day a soldier parade took place to change the guards at the town's southern walls. Since the San Sebastián Day was the first festival heralding the upcoming Carnival, it's no surprise that some youths in Carnival mood followed them aping their martial manners and drumrolls, using for the purpose the buckets left at the fountains. In the period spanning the 1860s and 1880s the celebrations started to shape as we know them today with proper military style outfits and parades and the tunes fashioned by music composer Raimundo Sarriegui.
