Basílica de la Merced, Minor basilica in San Miguel de Tucumán, Argentina

The Basílica de la Merced is a neocolonial church at the corner of Virgen de la Merced and 24 de Septiembre in San Miguel de Tucumán. Its white facade has a large recessed arch with a grid-patterned window and a statue niche above the doors, flanked by two towers with light blue domes and crosses; a larger blue dome rises behind. The current building, with a facade by Manuel Luis Graña, was inaugurated on 24 September 1950.

The Mercedarian Order built its church and convent in Ibatín after the city's 1565 founding; when San Miguel de Tucumán moved to its present site in 1685, the order received the corner of Virgen de la Merced and 24 de Septiembre, and in 1687 the Cabildo named the Virgin Patron and Advocate of the city. The present building is the fourth on the site: begun in 1834, abandoned in 1845, resumed in 1865 and blessed in 1880, it was partly demolished in 1914 and fully in 1927. Alfredo Guzmán and Guillermina Leston paid for the current church, inaugurated on 24 September 1950, with a facade by Manuel Luis Graña.

The basilica has been a central place of worship for Catholics in Tucumán since its establishment, drawing pilgrims who venerate the Virgin of Mercy. Daily masses and religious ceremonies here remain important to the spiritual life of the city.

The church sits at a central intersection and is open daily to visitors, making it easy to locate and enter. Regular mass services are held, so visiting during posted hours and being respectful during services ensures a good experience.

The gold-handled staff Belgrano gave the Virgin after the 1812 battle is kept here, but the church also preserves the image of Our Lady of Mercy that he named General of the army. The camarín holding the image was declared a National Historic Monument in 1957.
