Humaitá Fortress

Humaitá Fortress sits on a sharp bend of the Paraguay River and extends across several kilometers with earthworks and artillery positions. The site shows the remains of these defensive structures that once controlled river traffic.

The fortress was built between 1854 and 1862 under Carlos Antonio López to protect river access near Asunción. It played a key role during the war from 1864 to 1870 as a strategic river control point.

The fortress contained a church that served as a spiritual center for soldiers stationed here. The presence of this religious space reflected how faith played a practical role in the daily life of those defending the position.

The site houses a museum with objects from the war, including cannons and historical artifacts that visitors can examine. The location on the river bend makes it possible to walk through the grounds and see the Paraguay River from various points.

The fortress used an innovative defense system with a chain boom stretched across the river and contact mines to stop enemy ships from passing. This obstacle forced attacking vessels to take detours or slow down, making them vulnerable to attack.
