Bom Retiro (district of São Paulo) in the context of Estação da Luz

São Paulo (/ˌsaʊ ˈpaʊloʊ/; Portuguese: [sɐ̃w ˈpawlu] ; Portuguese for 'Saint Paul') is the capital city of the state of São Paulo, as well as the most populous city in Brazil and in the Americas. Listed by the Globalization and World Cities Research Network (GaWC) as an alpha global city, it exerts substantial international influence in commerce, finance, arts, and entertainment. It is the largest urban area by population outside Asia and the most populous Portuguese-speaking city in the world. The city's name honors Paul the Apostle and people from the city are known as paulistanos. The city's Latin motto is Non ducor, duco, which translates as "I am not led, I lead".

Founded in 1554 by Jesuit priests, the city was the center of the bandeirantes settlers during Colonial Brazil, but it became a relevant economic force only during the Brazilian coffee cycle in the mid-19th century and later consolidated its role as the main national economic hub with industrialization in Brazil in the 20th century, which made the city a cosmopolitan melting pot, home to the largest Arab, Italian, and Japanese diasporas in the world, with ethnic neighborhoods like Bixiga, Bom Retiro, and Liberdade, and people from more than 200 other countries. The city's metropolitan area, Greater São Paulo, is home to more than 20 million inhabitants and ranks as the most populous in Brazil and one of the most populous in the world. The process of conurbation between the metropolitan areas around Greater São Paulo also created the São Paulo Macrometropolis, the first megalopolis in the Southern Hemisphere, with more than 30 million inhabitants.

Sé is the name of the most central borough in the city of São Paulo, in Brazil, divided in eight districts. The name comes from the presence of São Paulo Cathedral (Catedral da Sé) in the borough, and it is also the name of the central square (Praça da Sé). Also located in the Sé are the Pátio do Colégio, site of the foundation of the city in 1554, the São Paulo stock exchange (the Bovespa), the mayor's palace and other historical buildings, including the Municipal Theater of São Paulo, the São Paulo Music Hall (Sala São Paulo) and the central railway Luz Station (Estação da Luz).

Immigrant groups established in the Sé borough include Italians (in Bela Vista), Japanese (in Liberdade), and Jews (in Bom Retiro). Sé is also the borough with the largest number of subway stations. There are many areas of popular commerce, like the 25 de Março Street (one of the most popular area of commerce in Brazil, though often illegal), and high-class areas such as Pacaembu and Higienópolis. The famous Paulista Avenue (Avenida Paulista) is the southwest limit of this borough, with the borough of Pinheiros.

Armênia, originally known as Ponte Pequena, is a metro station on São Paulo Metro Line 1-Blue, located in the district of Bom Retiro, in São Paulo.
