Campo Mourão
Campo Mourão lies on the open plateau of western Paraná, where grassy campos broke up the forest cover of the Paraná interior. In 1765 the valley between the Ivaí and Piquiri rivers was called Campos do Mourão, and travellers and cattle drovers rested there on journeys through the Guairá country. Kaingang communities had used the forest and river valleys long before, and the open pasture drew herds moving between the coast and the southern frontier.
