This map shows the Tietê River, which runs for 1,100 kilometers through the southeastern Brazilian state of São Paulo before connecting with the Paraná River, South America’s second longest river. Although the source of the river is located near the sea, the topography of the region forces the river to flow into the interior of the continent. Brazil’s largest city, São Paulo, grew up along the banks of the Tietê. Brazil -- History -- Colonial Period, 1500-1822; Iguatemi River; Rivers; Tietê River; Waterfalls
