In this guide
Humaitá is where you see what the Triple Alliance War left behind: the ruined church of San Carlos Borromeo, the museum in Marshal López's former barracks, the remains of the river batteries on the Paraguay River and, a few kilometres away, the trenches of Curupayty. The town is 40 km south of Pilar (opens in a new tab) on a dirt road, so Pilar or one of the local guesthouses is your base. Half a day covers the essentials; a full day lets you add the surroundings.
The ruins of San Carlos Borromeo
This is Humaitá's emblem, the symbol of the town (opens in a new tab). Carlos Antonio López had the church built, it opened on 1 January 1861 (Wikipedia (opens in a new tab)), and Brazilian artillery destroyed almost all of it during the war (Última Hora (opens in a new tab)). The ruins are national cultural heritage (La Nación, 2025 (opens in a new tab)), now managed and maintained by the town hall under an agreement with Senatur, the national tourism office.
- When: early morning or late afternoon. Summer heat reaches 40 °C (opens in a new tab) and shade is scarce.
- What to look for: the façade and bell tower still standing, with the river behind.
Museum of Marshal López's former barracks
Housed in López's old barracks, it has three rooms of battlefield relics (opens in a new tab): rifle bullets, cannons, stirrups, spurs and swords. Displays use technology to recreate the military campaigns and cover women's role in rebuilding the country (Última Hora, 2025 (opens in a new tab)). Visits are guided (opens in a new tab).
- Note: the town hall closed it in early 2025 and later reopened it (opens in a new tab). No hours are published, so ask as soon as you arrive.
Batteries and riverside remains
Humaitá was the fortress that held back the Allied fleet at the river bend. You can still see remains of the Londres Battery, Itá Puntã and the Brazilian barracks at Tuyucué (opens in a new tab). Ask at the museum how to reach each one; they are spread around town and along the bank.
Next to the ruins, Senatur began building a riverside pier and lookout (opens in a new tab) in late 2025, with a 45 m walkway. Ask whether it is open yet: it would be the best spot to take in the river and the fortress position.
Around town: Curupayty and the history route
- Curupayty trenches. About 5 km south (opens in a new tab), where General José E. Díaz won the battle of 22 September 1866 (opens in a new tab). The shortest outing from town.
- Ycuá de López, the field-hospital site and Yataity Corá. ABC Color lists them among Humaitá's historic sites (opens in a new tab). López and Argentina's Bartolomé Mitre met at Yataity Corá on 10–11 July 1866 without reaching a deal (ABC Color (opens in a new tab)).
- Paso Pucú. López's third command post, with a field hospital, a cemetery with a chapel, a lookout tower and wells (ABC Color (opens in a new tab)), on the history route towards Paso de Patria (opens in a new tab).
- Tuyutí. Reached on the Pilar–Humaitá road (opens in a new tab), so stop on the way in.
All of these are on dirt roads; after rain, ask before you drive.
The town: architecture, river and crafts
- Hotel Municipal. An Italianate building from the late 19th century (opens in a new tab), right beside the ruins (La Nación (opens in a new tab)).
- A fishing town. The mayor says 80% of residents fish (opens in a new tab); catches include surubí, dorado, pacú and mandi'i (Wikipedia (opens in a new tab)).
- Crafts. Burlap pictures, loofah goods, rustic tapestries and crochet (Wikipedia (opens in a new tab)).
Getting there, where to stay and when
- Distance: Humaitá is 269 km from Asunción (opens in a new tab) via the PY19 and Pilar. The last 40 km from Pilar are dirt and become impassable in rain; work started in July 2026 (opens in a new tab) to pave the 33.6 km Pilar–Humaitá road.
- Where to stay: four Senatur-registered guesthouses plus the municipal hotel (opens in a new tab), or stay in Pilar: see things to do in Pilar.
- When: tour buses bring around 500 visitors on weekends (opens in a new tab), more at Holy Week. Go on a weekday for quiet.
- A one-day plan from Pilar: see our Humaitá day trip.
