Fiesta de la Primavera de Dolores in Dolores
Fiesta Nacional de la Primavera is Dolores' student-organized spring festival, running since the 1960s and now held on the second Sunday of October, bringing together representatives from the city's secondary schools in one of Soriano department's best-known annual celebrations of youth, community and civic identity in western Uruguay.
Dolores, the seat of the Soriano department in western Uruguay and, by some historical accounts, tied to a Spanish colonial settlement founded as early as 1574, hosts an annual celebration known as the Fiesta Nacional de la Primavera, a tradition Wikipedia's own city article traces back to the 1960s.
