19th century, a procession was held from the Santa Maria Church in the Old Part to the San Sebastián Church in the district of Antiguo, while later limited due to weather conditions to the walled area. The event finished with a public dance accompanied by the military band's flutes and drums. Every day, a soldiers' 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, exuberant youths began to follow them, aping their martial manners and drumrolls, using the buckets left at the fountains as drums. The celebrations started to take their current form in the period from the 1860s to 1880s, with real military style outfits and parades and music by composer Raimundo Sarriegui. Adults usually have dinner in txokos ("gourmet clubs"). Traditionally, these admitted only men, but now even the most conservative ones allow women on the "Noche de la Tamborrada". They eat sophisticated meals cooked by themselves, mostly composed of seafood (traditionally elvers, now no longer served due to its exorbitant price) and drink the best wines. La Semana Grande/Aste Nagusia A festival, La Semana Grande in Spanish and Aste Nagusia in Basque ("The Big/Main Week"), is held every year in mid-August. A major international fireworks competition is held during the festival, in which teams representing various countries and cities put on a fireworks display each night over the bay, with the winner of the contest announced at the end. The displays are sometimes accompanied by a full live orchestra performing on the boardwalk. Attendees often claim spots along the beach and bay hours in advance. The festival also includes a parade of marching bands, entertainers on stilts, and Basque processional giants every afternoon. Semana Grande attracts a lot of domestic and international tourism. Basque Week Running for several decades at the beginning of September, Basque Week features events related to Basque culture, such as performances of traditional improvising poets (bertsolaris), Basque pelota games, stone lifting contests, oxen wagers, dance exhibitions, and a cider tasting festival. The centrepiece of the festival is the rowing boat competition, in which teams from different towns around the Bay of Biscay compete for the Flag of La Concha. Thousands of supporters from these coastal locations fill the city's streets and promenades overlooking the bay to follow the event, especially on the Sunday of the final race.
