History
Founded in 1531, Cananéia is considered by some to be the oldest city in Brazil (5 months before the foundation of São Vicente) but due to the lack of official documentation proving this fact, São Vicente is officially the oldest city in Brazil. The historic center of Cananéia still preserves the architectural styles adopted by the first houses from the colonial period to the end of the 19th century.
