Porto's Queima das Fitas traces its origins to the beginning of the 1940s, and is a major event in the first week of May, before the beginning of the study period preceding the school year's last exams. The week comprehends 12 events, starting with the Monumental Serenata on Sunday, reaching its peak with the Cortejo Académico on Tuesday, when students from the universities and other higher education institutions of the city march through the downtown streets till they reach the city hall, where they're greeted (and greet back) by the Mayor. During every night of the week a series of concerts takes place on the Queimódromo, next to the city's park; here it's also a tradition for the students in the second last year to erect small tents where alcoholic beverages are sold in order to finance the trip that takes place during the last year of their course.
