Fiesta del Inmigrante in Colonia Valdense/Nueva Helvecia
Nueva Helvecia and neighboring Colonia Valdense were founded by Swiss and Waldensian Piedmontese immigrants in 1862 and 1858 respectively, a heritage the twin towns already mark through confirmed events like the Fiestas Suizas each August, though a dedicated source specifically confirming a separate Fiesta del Inmigrante was not found.
The towns of Nueva Helvecia and Colonia Valdense sit just five kilometers apart in the Colonia department, and both trace their origins to specific, well-documented waves of nineteenth-century European immigration that reshaped this corner of southwestern Uruguay.
