La Santísima Trinidad de Paraná (The Holy Trinity of the Parana) is one of the most prominent ruins of the Jesuit missions in Paraguay, located near the town of Encarnación, just across the river from Posadas, Argentina. Founded in the early 18th century, it was part of a network of reducciones—settlements established by Jesuit missionaries to convert and protect Indigenous Guaraní communities while introducing European education and religion.
Today, the site is a UNESCO World Heritage Site and features remarkably well-preserved stone buildings, including a central church, cloisters, workshops, and a central plaza. What sets Trinidad apart is the scale and craftsmanship of its stone carvings, particularly the religious iconography and detailed friezes still visible in the ruins. Though uninhabited for centuries, the site remains a key symbol of the unique cultural synthesis between European missionaries and Indigenous peoples during the colonial era.
We visited La Santísima Trinidad de Paraná on a cross-border day trip from Posadas, before crossing back into Paraguay for good a few days later via Ciudad del Este. Here’s how that little excursion unfolded, along with some practical tips you might find useful if you’re planning something similar.

The Border Crossing from Posadas to Encarnación
The cities of Posadas and Encarnación are connected by a 2 km bridge spanning the Paraná River, which you can cross by either train or bus. We tried both—taking the train in the morning and returning by bus in the evening. The bus turned out to be not only more expensive (11,000 PYG ≈ €1.30 vs. 1,380 ARS ≈ €1 for the train), but also way slower, at least during rush hour. We were completely stuck in traffic for nearly an hour, so much so that we even asked the driver to open the door so we could walk the rest of the way, but he wouldn’t.
In hindsight, there’s really no good reason to take the bus. We only did so to save time and taxi money and avoid the extra time it would’ve taken to get back to the train station in Encarnación, by foregoing the trip to Encarnación train station, which is some distance out of the center, but it backfired.
The train is cheap, quick, and comfortable. The Posadas train station is located here, about a 30-minute walk from the city center. At the time of our trip (May 2025), trains were running every half hour from 07:15 to 18:15. We arrived early, bought our tickets, and passed through immigration in a jiffy—no lines, no hassle. Within minutes, we were on board, and just eight minutes later, we stepped off in Encarnación.
Changing Money in Encarnación
In the four-plus months we’d spent traveling through Brazil, Uruguay, and Argentina up to that point, we’d hardly used cash at all. In those countries, cards are pretty much universally accepted, even by street vendors. But we already knew that Paraguay plays by different rules. So, we needed some dough.
Usually, the first people to greet you after a land-border crossing—even beating the taxi drivers—are the money changers. Not here. Outside the Encarnación train station, the only people waiting were touts from electronics stores. As we realized on the spot, Argentinians regularly cross into Paraguay to shop for cheap electronics, only to face thorough luggage inspections by Argentinian customs officers on the way back.
One of those touts volunteered to help us with forex for a tip. He first led us through the labyrinthine marketplace adjacent to the station. We visited a couple of gadget shops whose owners moonlighted as money changers. But they were only willing to buy dollars, not pounds, which was the only currency we currently happened to carry.
Still on the hunt, we hopped into his car and drove to an official exchange office downtown. But no luck there either—the staff refused to exchange our money because, as we’d just discovered, immigration had failed to stamp our passports. Apparently, this kind of thing isn’t all that rare in this part of the world. Missing stamps are a common headache, and it’s often up to the traveler to make sure everything’s in order, or risk running into trouble later.
We ended up back at the market, where we agreed with a shop owner to make a card payment—plus the bank’s and his fees—in exchange for cash.
From Encarnación to La Trinidad de Paraná
The bus station of Encarnación is located here, 3.5 km from the border train station. With our pockets filled at last, we shared a bit of their newfound content with our new friend and assistant, and letting him continue his touting, we took a taxi there.
The ticket from Encarnación to La Trinidad de Paraná cost 20,000 PYG (≈ €2.3). While waiting for the next departure, we grabbed some street food from one of the vendors roaming the station. Compared to what we’d lately been paying for meals in Argentina, this felt practically gratis. It crossed my mind to stock up on provisions before crossing the border back later.
The bus arrived 15 minutes late. We boarded, and exactly one hour later, hopped off near the historic site.
The Jesuit Mission Ruins of La Tranidad de Paraná
It took about 10 minutes to reach the site entrance from the bus stop on the main road. The ticket cost 40,000 PYG (≈ €4.60) and was valid for 72 hours. It also included access to the nearby Jesuit sites of Jesús de Tavarangue and San Cosme y Damián, which, unfortunately, we wouldn’t have time to visit.
If you intend to stay in the area and visit all three sites, here are some nice places to stay:

The ruins of La Santísima Trinidad de Paraná unfolded in front of us like something out of a dream half-remembered — familiar in its symmetry and stone, yet mysterious in its silence. Founded in the early 18th century by Jesuit missionaries, this was once one of the most important of the Reducciones Jesuíticas — settlements established to evangelize and protect the Guaraní people. Today, its crumbling walls and red sandstone facades remain as ghostly testaments to that audacious and paradoxical mission: to build a European-style Christian society in the heart of the South American jungle.
Despite centuries of weather and abandonment, the site is still visually commanding. The architecture is Baroque with indigenous influence, grand without being gaudy. Tall, arched walls frame an expansive courtyard, and remnants of intricate carvings cling to doorways and portals. One especially majestic altar, now exposed to the sky, still holds traces of the elaborate design that once shimmered with gold leaf and paint. Inside the church’s remains, the eye is drawn upward to where a stone dome once soared—until it collapsed in the 18th century, taking with it a large portion of the church roof and beginning the slow unraveling of the structure.
It’s remarkable to think this site was constructed almost entirely by Guaraní hands, under Jesuit supervision, but with native ingenuity. The signage inside the small on-site museum explains this fusion of cultural craftsmanship: European symmetry meets indigenous materials, with some decorative motifs taking creative liberties beyond classical norms. Fragments of columns and sacred sculptures are displayed there — the remnants of a building that was once vibrant with music, schooling, and ritual.
Now, the only music comes from the wind rustling through trees and the occasional squawk from above. Two hulking black vultures had stationed themselves on the highest remaining arch, where they loomed like winged gargoyles guarding a forgotten kingdom. They watched us with mild curiosity as we wandered through the site, not quite menacing, but certainly owning the place.
We were almost alone, save for one small tour group that briefly crossed our path. The stillness added to the gravity of the place. After a while, we stopped exploring and simply sat in the shade of the enormous tree that dominates the central courtyard. Its leafy canopy offered a perfect break from the heat, and for a few quiet minutes, we rested with our backs on the lush grass, listening to the breeze pass through centuries-old silence.
This was more than a visit to some old ruins. It felt like stepping inside a memory of something both majestic and mournful. A place once filled with purpose, now filled with time. After taking it all in, we caught the bus back to Encarnación. Before crossing the Paraná again later that evening, we took a leisurely stroll through the city.
