Retiro is a barrio or district in north-eastern Buenos Aires, Argentina, famous for its high-society inhabitants, the Santa Fe avenue shopping district, San Martín square, and the Retiro transportation hub, which features train, subway (Line C), and the main bus terminal, always teeming with commuters in weekdays.

The northern end of Florida Street is in the leafy San Martín square, surrounded by great palaces and hotels. The Retiro lowlands were the training grounds for José de San Martín's Granaderos corps, and modern-day San Martín square features a statue of the independence hero on horseback, as well as the memorial for the dead in the 1982 Falklands War (Spanish: Guerra de las Malvinas). Retiro is (together with Recoleta and parts of Palermo and Belgrano) a popular residential area for expatriate executives.

We recommend: San Martin square, San Martin Palace, Florida Street, National Museum of the Weapons, Military Circle, Monumental Tower. Museum of the Immigration.
