Posadas
A Foreigner’s Guide to Misiones
Posadas is the capital of Misiones Province in northeastern Argentina and home to more than 350,000 people, making it the political, administrative, and cultural center of the region. Located directly on the Paraná River, across from its sister city Encarnación in Paraguay, Posadas plays an important role as a border city and regional gateway.
Often described as the entrance to the subtropical rainforest of Misiones, Posadas connects urban life with rivers, red soil, and dense green landscapes typical of the Litoral region. It may not be a typical tourist city, but Posadas reveals its character to those who take the time to experience it.
A Glimpse into History
The roots of Posadas trace back to the early 17th century, when Spanish Jesuit missionaries founded the settlement of Nuestra Señora de la Inmaculada Concepción de Itapúa in 1615. This was part of the larger network of Jesuit reductions that once extended throughout the border region of present-day Paraguay, Misiones, and Brazil.
When the Jesuits were expelled from Spanish territories in 1767, many of these reductions, including Itapúa, were abandoned, leaving behind ruins and scattered communities. The area remained quiet for much of the 18th and early 19th centuries, but the Paraná River’s strategic importance as a trade route ensured it would not be forgotten.
By the mid-19th century, renewed interest in the region led to the founding of a new settlement (Trinchera de San José) on the riverbanks. In 1879, it was officially named Posadas, in honor of Gervasio Antonio de Posadas, Argentina’s first Supreme Director during the independence era. With the expansion of the Argentine railway and shipping networks in the early 20th century, the city grew rapidly, soon becoming the administrative and economic heart of Misiones Province.
Today, Posadas’s layered past is still visible in its colonial-style churches, the stories tied to its historic neighborhoods, and the pride locals take in both their indigenous roots and Argentina’s national history.
What to see in Posadas
Plaza 9 de Julio
The central square, framed by the Cathedral of San José, the Government House, and the Italian Society, is a natural gathering point. Events, live music, and markets often take place here, giving visitors a sense of the city’s rhythm.
Plaza San Martin
A quieter, shaded counterpart to Plaza 9 de Julio, this plaza honors General José de San Martín. It’s a favorite spot for locals to relax, children to play, students to read, and elders to share mate beneath tall trees.
La Bajada Vieja
The oldest neighborhood of modern Posadas, once the city’s main access to the river, is today known for its traditional houses and colorful street art. Steeped in legend, song, and memory, it remains one of the most atmospheric places in the city, especially at sunset.
Parque República del Paraguay
A symbol of friendship between Argentina and Paraguay, this green park includes an amphitheater, sculptures, and open lawns, perfect for relaxed afternoons.
Museo Regional Aníbal Cambas
Housed within Parque Paraguayo, this museum tells the story of Misiones, from Guaraní culture and Jesuit missions to colonial daily life and natural history.
Jardín Botánico Alberto Roth
A large reserve in southern Posadas dedicated to native flora of the Atlantic Rain Forest. With walking trails, interpretive signs, and picnic areas, it is a haven for birdwatchers, nature lovers, and anyone needing a break from the city.
More Than Meets the Eye
These highlights are just the beginning. The National University of Misiones has catalogued over 30 tourist attractions in Posadas, from historic houses and street art to cultural centers and hidden green spaces. In this blog, we’ll explore them one by one, uncovering the many layers of this city that most travelers only pass through.
Life Between Two Shores
Posadas is directly connected to Encarnación, Paraguay, via the San Roque González de Santa Cruz International Bridge. This closeness creates a daily cultural and commercial exchange, with families visiting across borders, shoppers crossing for deals, and traditions that flow both ways. The Guaraní language and heritage unite both cities, reminding visitors that this region is older and richer than any borderline. For travelers, a day trip across the bridge to Encarnación adds another dimension to the experience of being in Posadas.
