Arroio do Tigre
The principal settlement of the region occurred around 1900, when German settlers migrated from the "Colônias Velhas" region (called "die Altkolonie", in the regional German dialect Riograndenser Hunsrückisch) of Santa Cruz do Sul and the surrounding areas. Afterwards there was an influx of Italian Brazilians and Portuguese Brazilians. In 1920 it began to be known as Vila Tigre, and found its first commercial buildings, Catholic and Evangelical churches, and later, the Hospital Santa Rosa de Lima and Colégio Sagrado Coração de Jesus. In 1920 an agricultural cooperative, Cooperativa Agrícola Mista Linha Cereja (COMACEL), was founded, which is still active.
