Basílica Nuestra Señora del Rosario

About Basílica Nuestra Señora del Rosario

📜 History

The Dominicans arrived in Buenos Aires in 1606 and occupied the block where the basilica stands today. Construction of the current temple began on June 29, 1751, according to the plans of the architect Antonio Masella, of Turinese origin. The church was consecrated on October 17, 1783, although the finishing work on the roof and the left tower remained incomplete at that time. The works continued until 1856, with the later participation of Francisco Álvarez and Manuel Álvarez de Rocha. During the British Invasions of the Río de la Plata, the convent was the scene of the Battle of Santo Domingo on July 2, 1807, when British troops entrenched themselves in the eastern tower. The marks from the cannon shots remain visible on the tower to this day. In 1822, during ecclesiastical reforms, the Dominican friars were expelled; between 1826 and 1854 the convent housed the Museum of Natural History under the direction of Paolo Ferrari. The Dominicans returned in 1835 by decree of Juan Manuel de Rosas. In 1910, Pope Pius X elevated the temple to the category of basilica, and on October 8, 1922, the image of the Virgin received a papal coronation.

🏛️ Architecture

The building was designed by Antonio Masella, an architect of Turinese origin, and its construction began in 1751. The project was continued by Francisco Álvarez and Manuel Álvarez de Rocha. The temple corresponds to the Neoclassical style with colonial elements and features a three-nave floor plan: the central nave has a barrel vault, and a dome rises over the transept. The interior of the main nave is clad in marble, with sculpted reliefs on the columns and marble confessionals. In 1894, the architects Auguste Plou and Oliver intervened on the facade, adding a broken pediment at the top. One of the two towers preserves the impacts from the cannon shots of 1807; the original bullets were replaced with wooden plugs as a memorial. The main altar was destroyed in 1955 and replaced with a contemporary one. The side chapels preserve altarpieces from the 18th and 19th centuries. The adjacent convent, whose construction began on February 11, 1792 and was completed around 1805, is part of the heritage complex and is integrated into the same historic block.

⭐ Key Facts

The basilica houses one of the most representative historical collections in Argentina related to the British Invasions. Four British flags captured after the First Invasion of 1806 and donated by Captain Santiago de Liniers are preserved inside, along with standards of the 71st Regiment of Highlanders and the Royal Navy. In the atrium stands the mausoleum of General Manuel Belgrano, creator of the Argentine flag, inaugurated in 1903 with a sculpture by Ettore Ximenes; Belgrano had been a benefactor of the temple and was originally buried under a slab at ground level. The image of the Virgin of the Rosary, brought from Peru and over four hundred years old, is the central object of veneration. On October 8, 1922, it received a papal coronation. The temple was declared a National Historic Monument on May 21, 1942. Between 1828 and 1834, the astronomical observatory installed in the convent was directed by Octavio Fabricio Mossotti. The patronal feast of Our Lady of the Rosary is celebrated every October 7.

The basilica is located at the corner of Avenida Belgrano and Defensa, in the historic center of Buenos Aires. The complex allows visitors to explore different layers of Argentine history in the same space: the mausoleum of Manuel Belgrano, the flags captured during the British Invasions, the centuries-old image of the Virgin of the Rosary, and the architecture of a building dating from the colonial era. The temple is open for worship and visits, and every October 7 the community gathers to celebrate the patronal feast.
