Iglesia de San Miguel, Renaissance church in San Nicolás, Buenos Aires, Argentina.

The Iglesia de San Miguel Arcángel is a Catholic church at the corner of Bartolomé Mitre and Suipacha streets in the San Nicolás neighborhood of Buenos Aires. It has a single tower, completed around 1853, and a façade remodeled between 1912 and 1918 by Italian architect Augusto Ferrari with Venetian mosaic in a Neo-Renaissance style. It was declared a National Historic Monument in 1983.

Construction began in 1782 under the name Nuestra Señora de los Remedios and opened in 1788. Between 1912 and 1918, architect Augusto Ferrari undertook a major renovation, transforming the facade in Neo-Renaissance style.

The church keeps the name of the Hermandad de la Santa Caridad de Nuestro Señor Jesucristo, founded on 13 March 1727 by Juan Guillermo González y Aragón to assist the sick and dying. Its main altar holds an image of Nuestra Señora de los Remedios brought from Cádiz. The brotherhood moved to the Monserrat church in 1791, and Rivadavia closed it in 1822, creating the Sociedad de Beneficencia.

The church stands at the corner of Bartolomé Mitre and Suipacha streets in the San Nicolás neighborhood, a few blocks from Plaza de Mayo and Avenida 9 de Julio. The entrance faces Bartolomé Mitre, and the single tower makes the building easy to pick out along the street. The interior is visited on foot during opening hours, and access is interrupted while services are held.

The single tower was only completed around 1853, roughly 65 years after the church opened in 1788. During the second British invasion, Lieutenant Colonel Duff's column tried to force the church door on the street then called de la Piedad, lost some thirty men and withdrew, as he testified at Whitelocke's trial.
