« Mendoza is an oasis at the foot of the Andes, and without the canals of its ancient inhabitants, it would not exist. »— Ricardo Rojas, La restauración nacionalista, 1909
Your quest begins at Mendoza's Área Fundacional, on Plaza Pedro del Castillo. It was here, on the ruins of the old destroyed city, that the foundations of San Juan de la Nueva Ciudad de Mendoza were laid in 1561 by Pedro del Castillo. You'll unearth the first clues of the Huarpe past, the indigenous people of the Cuyo region, whose ancestral irrigation canals were adopted by the Spanish to create the oasis that still defines the city of Mendoza. Exploring this archaeological site reveals layers of complex history, blending indigenous and colonial cultures.
Continue to the Ruinas de San Francisco, remnants of one of Mendoza's oldest churches, destroyed by the 1861 earthquake. These ruins bear witness to nature's destructive force and the resilience of the Cuyo population. The church, founded in the 17th century, housed colonial art treasures and served as a spiritual center. As you walk through its collapsed walls, you discover hidden inscriptions and symbols that refer to the Huarpe funeral rites, often mixed with the Catholic practices of the early settlers.
Plaza San Martín, erected in honor of Liberator José de San Martín, is your next stop. This central square, created after the city's refoundation, represents the civic heart of the new Mendoza. It embodies the transition from a colonial city to a modern metropolis in the 19th century. Here, you examine statues and monuments to uncover coded messages left by archaeologists of the time, who, like you, sought to preserve the memory of Cuyo's original peoples in the face of advancing modernity.
Your journey then takes you to Peatonal Sarmiento, a vibrant commercial artery of Mendoza. Although modern, this pedestrian street connects key points in the city center and allows you to observe the eclectic architecture of the late 19th and early 20th centuries. It is in the details of the facades, wrought iron grilles, and mosaics that you identify floral and geometric patterns reminiscent of Huarpe textile craftsmanship and pottery, proof that their culture continued to influence local aesthetics long after Spanish colonization.
Your odyssey concludes at the Basílica de San Francisco, a major religious edifice in Mendoza, where the Virgen del Carmen de Cuyo, patroness of the Army of the Andes, rests. This basilica, rebuilt after 1861, symbolizes the city's renewal and the fusion of cultures. Exploring its naves, you assemble the final fragments of your investigation, revealing how Huarpe traditions survived, sometimes hidden, sometimes integrated, at the heart of Mendocinian identity. You bring back to the La Plata museum a complete picture of a people's heritage, now etched into the stones and soul of Mendoza.
