Saint Martin square is located in Retiro neighborhood really close to the city center. Retiro is a district in north-eastern Buenos Aires, 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 (Microcentro) 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, as well as the memorial for the dead in the 1982 Falklands war. The park "San Martin" was previously named Plaza Británica but was named Plaza Fuerza Aérea Argentina in 1982.

As a "Big Ben" copy, the Torre de los Ingleses ("British Tower") is a monument donated by the Anglo-Argentine community for the independance of 1910 centenary celebrations, with the relief of the British arms at its bottom. This monument has been the object of several acts of sabotage in the wake of the aforementioned conflict.
