The story that haunts this land
Your quest begins in Plaza 25 de Mayo, the vibrant heart of Corrientes. Founded in 1588 by Juan Torres de Vera y Aragón, this 2-hectare square has been the scene of major civic ceremonies since the 19th century. It was here, as in other Argentine cities, that the events of the May 1810 revolution were proclaimed. You will decipher the first clues near the central fountain, observing the historic buildings surrounding it, including the Casa de Gobierno, seat of the provincial executive power. This essential starting point for your Corrientes historical circuit is a living testament to the city's past.
Continuing your itinerary, you will reach the Casa de Gobierno de Corrientes, a neoclassical building constructed in 1858. Its interior frescoes, created in 1930 by local painter Ceferino Balbín, depict Correntina history and are a valuable source of clues. The 50-meter-long facade, adorned with Ionic columns and restored in 1990, holds symbols that your augmented reality will reveal. It was within these walls that the Pact of Corrientes was signed in 1820 between Artigas and local caudillos, a crucial event for the independence of northeastern Argentina. Your interactive visit Corrientes plunges you into the heart of these founding moments.
Your journey then leads you to the Iglesia Nuestra Señora de la Merced, a monument of Corrientes' National Historical Heritage. Built between 1859 and 1868 in a Neo-Gothic style by Italian architect Giacomo Colombino, this church impresses with its 45-meter-high bell tower, visible from the Paraná. The interior houses the image of the Virgin of Merced, patron saint of the city since 1630. Restored after the Paraná floods in 1982, it is an emblem of the city's resilience against the river's whims, a key element of the Ruta del Paraná and the history of Corrientes.
On your way to Costanera General San Martín, you will discover the Monumento a la Batalla de Riachuelo. Inaugurated in 1967, this 8-meter-high bronze monument, sculpted by the monumental, commemorates the naval battle of June 11, 1865, during the War of the Triple Alliance. This decisive Argentine victory against Paraguay secured control of the Río Paraná, a major strategic stake. Located less than 1 km from Plaza 25 de Mayo, it is a tangible reminder of Corrientes' military importance in the region's history. Your Corrientes treasure hunt will lead you to explore the narratives of this period.
Your adventure concludes at the Convento de San Francisco, built in 1630 by the Franciscans, one of the city's oldest buildings. This 30-meter-long church with its inner cloister, restored in 1945, served as a refuge during the Paraguayan invasions in 1810-1811. It now houses the Juan Torres de Vera y Aragón museum since 1970, offering a perspective on the legacy of Corrientes' founder. By connecting these points of the Corrientes historical circuit, you will have assembled the fragments of a message spanning centuries, revealing the depth of this northeastern Argentine city's history and its unbreakable link to the Paraná.
