Vibrant São Paulo is among the world's most populous cities. Brazil's financial center, it has abundant cultural institutions and a rich architectural tradition. Its iconic buildings range from the 1929 Edifício Martinelli skyscraper and the neo-Gothic Metropolitan Cathedral to modernist architect Oscar Niemeyer’s curvy Edifício Copan. The colonial-style Pátio do Colégio church marks where Jesuit priests founded the city in 1554.
