Pinheiro Machado

Pinheiro Machado is one of the most ancient towns in the state of Rio Grande do Sul. Until 1830, the area was owned by the city of Rio Grande. After it became a part of Piratini city, separating on February 24, 1879, by the name of Nossa Senhora da Luz, or Nossa senhora da Luz das Cacimbinhas. The occupation of this town, according to records, began by the brigadier Rafael Pinto Bandeira, about 1765. The first inhabitants were the azorean Tomás Antonio de Oliveira and José Dutra de Andrade, who owned "allotments" (Portuguese: sesmaria (pt)) of land at Coxilha do Veleda, in 1790. According to the legend, Dutra de Andrade had lost his vision and then, he made a promise that if he would recover his vision washing his eyes on the miraculous water of the well located there, he would order the building of a chantry in honor of Nossa Senhora Aparecida and so, the miracle happened. After the chantry, a parsonage was created in 1851.
