Basílica Nuestra Señora de La Merced

About Basílica Nuestra Señora de La Merced

📜 History

The Mercedarian friars arrived in the territory that is now Argentina in 1589 and received a plot of land granted by Juan de Garay during the founding of Buenos Aires in 1580. In 1603 they built a small adobe church with a wooden and thatch roof, along with the Convento Grande de San Ramón Nonato, founded that same year by fray Pedro López Valero. In 1721 the decision was made to construct a permanent and larger-scale building. The works, designed by Giovanni Andrea Bianchi and Giovanni Battista Prímoli, were partially completed in 1733 with the inauguration of the nave, dome, presbytery, and transept; the structure was substantially finished in 1779. In 1806, from the atrium of the temple, Santiago de Liniers organized the attack on the Plaza Mayor during the First English Invasion. On September 12, 1812, José de San Martín married María de los Remedios de Escalada inside the temple. Between 1894 and 1900, the architect Juan Antonio Buschiazzo directed a comprehensive renovation, the result of which was inaugurated on April 24, 1900. In May 1942 a presidential decree declared the building a National Historic Monument, and between 2001 and 2007 the National Secretariat of Public Works carried out a new restoration.

🏛️ Architecture

The current building corresponds to an eclectic style, the product of successive construction and renovation campaigns over nearly three centuries. The original 18th-century plans belong to the architects Giovanni Andrea Bianchi and Giovanni Battista Prímoli, who designed a floor plan with a nave, dome, presbytery, and transept, inaugurated in 1733. The complex incorporated Baroque elements in that first stage. Between 1894 and 1900, the architect Juan Antonio Buschiazzo, born in Italy in 1846, carried out the comprehensive renovation that defined the temple's current appearance, incorporating Neoclassical influences; the remodeled structure was inaugurated on April 24, 1900. In 1954, Andrés Millé directed the restoration of the narthex. The basilica is located at Reconquista 207, in the San Nicolás neighborhood of Buenos Aires, near the Plaza de Mayo. One of its towers housed an astronomical observatory operated by Adolfo Jaeggli and Isidoro Diavet in 1859, reflecting the building's relevance beyond its religious function during the 19th century.

⭐ Key Facts

The basilica occupies a central place in the religious and civil history of Argentina. The Mercedarian order, present in the territory since 1589, was one of the first religious communities established in Buenos Aires. The temple is dedicated to Nuestra Señora de la Merced, whose feast day is celebrated on September 24. Among the historical events linked to the building is the marriage of José de San Martín to María de los Remedios de Escalada, celebrated on September 12, 1812, an event of particular weight in national history given San Martín's role in Argentine independence. Bernardino Rivadavia, who would become the first president of Argentina, married Juana del Pino in the temple in 1809. In 1829 it was designated the Parroquia de Catedral al Norte. Pope Benedict XV elevated it to the rank of Minor Basilica in 1917, a distinction that recognizes its liturgical and historical significance. In 1834, the convent attached to it housed a school for orphaned girls, and in 1892 the building served as a polling place in a presidential election.

Located in the historic heart of Buenos Aires, a few meters from the Plaza de Mayo, the basilica preserves in its naves more than four centuries of Argentine religious and civil life. The building holds the memory of marriages that marked national history, military episodes, and generations of faithful linked to the Mercedarian community. The eclectic architecture that defines its current appearance reflects various interventions from the 18th century to the early 20th century. Its status as a National Historic Monument and Minor Basilica makes it a reference point for the city's religious and architectural heritage.
