While Rio de Janeiro is Brazil's most iconic city, it is not the oldest. That distinction belongs to São Vicente, founded on January 22, 1532 by Portuguese explorer Martim Afonso de Sousa.
São Vicente, located on the coast near Santos, preserves its historic core, including the Church of Nossa Senhora da Conceição (1532) and the Pátio do Colégio (site of the first Jesuit school). It is the "Cradle of Brazilian Nationality."
Rio, founded 33 years later, grew to become the imperial and republican capital, overshadowing its older sibling in fame—but not in antiquity.
