Machine translation of the Portuguese Wikipedia article (November 2026 version).
Poá is a Brazilian municipality in the state of São Paulo, located in the Metropolitan Region of São Paulo and the Alto Tietê. It is considered a municipality of tourist interest under state legislation and is self-styled as a Hydromineral Resort (Estância Hidromineral) under municipal legislation.
The main sector of Poá's economy is services, since the establishment of polluting industries has been hindered since 1970, the year it became a resort town. In territorial terms, it is one of the smallest municipalities in the state of São Paulo (larger only than Águas de São Pedro and São Caetano do Sul). The vertical development of the city centre is discouraged, in order to preserve the small-town atmosphere the city has, with narrow streets and the preservation of several old buildings.
