With the constant traffic of the troops, one of the river crossings transformed into
a big obstacle making it difficult for them to pass. In the rainy season, when
the waters of the river were high, the troops were obliged to wait until the
waters came down and they could pass this part of the river, which was usually
full of mud (barro). By the time, one of those places transformed into a tiny ranch
which could offer a basic infrastructure for the troops during their stay.
Because of the mud, they first called this place "Barreiro" and later when the
chapel of São José was built, they extended its name to São José do Barreiro.
When the gold rush came to an end, coffee should initiate the next
economic cycle in Brazil. Due to the excellent fertility of the
soils from the Paraiba valley and the
proximity to the ports of Paraty and Mambucaba, many coffee farms opened during the
18th century in the region and São José do Barreiro became considerably rich at this time.
The beautiful buildings and houses of the coffee farms remember of the times when
São José do Barreiro played an important role in São Paulo´s coffee industry.
Actually São José do Barreiro´s economy is centered in agriculture
(rice, feijão beans, mice, manioc and sugar cane), milk production, cattle and
ecotourism which every year becomes more important due to the large number of
attractions either cultural - historic (old coffee farms and houses) or natural
(Serra da Bocaina, trails and waterfalls).
