Plaza de Miserere is one of the main plazas (squares) of Buenos Aires, Argentina. It is located alongside the Once de Setiembre Station of the Ferrocarril Domingo Faustino Sarmiento (Sarmiento railroad) in the heart of the Balvanera neighborhood.
The square lies on the former site of a mansion known as the Quinta de Miserere. Around 1814, it was known as Mataderos de Miserere (Slaughterhouses of Miserere), Hueco de los corrales (Hole of the corrals) in 1817, and Mercado del Oeste (Western Market) by 1850. It was also known as Mercado (or Plaza) 11 de septiembre (11th of September Market or plaza); the name Plaza Miserere dates from 1947.
The plaza was the site of skirmishes during the British invasions of 1806. It was the site of the defeat of the troops under Santiago de Liniers during the second invasion of 1807.
The market functioned until 1882, when Mayor Torcuato de Alvear began the demarkation of the plaza. The neighboring Once Terminal was inaugurated in 1898. The square underwent an important remodel in 1913, when a Line A station for the Buenos Aires Metro was built underneath. This station was officially named after the square above it, but like the square itself became more popularly known as Plaza Once.
Plaza Miserere (officially Plaza de Miserere) is a station on Line A of the Buenos Aires Underground. The station is located between Alberti and Loria / Pasco stations on the A line underground. Plaza Miserere has interchange with Once underground station of the H line and connection to the Sarmiento line commuter rail service within Once railway station, the central station of the Domingo Faustino Sarmiento Railway.
It is located at the intersection of Rivadavia and Pueyrredón avenues, under the popular Plaza Miserere, in the neighborhood of Balvanera. The station zone is a shopping precinct and in its vicinity are the French Hospital and the Once railway station of the Sarmiento Railway. This station belonged to the first section of Line A opened on 1 December 1913, linking this station and the Plaza de Mayo station.
In 1997 the station was declared a national historic monument.
When the Anglo-Argentine Tramways Company (Compañía de Tranvías Anglo-Argentina, in Spanish) inaugurated on 1 December 1913 its Line 1 (Today, Line A of the subway), Plaza Once—today Miserere—was the terminus, and thanks to an agreement with the company's Buenos Aires Western Railway (Ferrocarril Oeste de Buenos Aires, in Spanish)—Sarmiento today—it was possible the design and construction of the subway station with the possibility of being used in a synchronized manner for both modes of transport. To do this, it was built with 6 tracks (4 for the subway and 2 for the train) and 4 platforms (2 lateral and two central).
