Sunken in the 19th Century, the Tamandathay Ship Lies in the Tietê, Near Itapura, Preserving Memories of the Paraguayan War and Attracting Divers, Historians, and Curious Visitors from the Interior of São Paulo
More than 670 km from the capital of São Paulo, in the interior of the state of São Paulo, the Tietê River reveals a little-known chapter of Brazilian history. Beneath its waters, outside the metropolitan area, lie the ruins of an old military ship from the Empire era, now considered by many a true submerged museum.
The scene surprises not only for its historical significance but also for the possibility of direct contact with remnants of a past marked by conflicts, displacements, and profound transformations in the country.
A Hidden Heritage in the Waters
The site where the remains of the vessel are located is near the city of Itapura, on the border with Mato Grosso do Sul.

There, divers can observe part of the ship’s structure and imagine what life on board was like in a time when rivers were essential routes for transportation and communication.
The cleaner and clearer waters of the middle course of the Tietê help preserve what remains of the vessel, turning the space into a point of interest for athletes, researchers, and history enthusiasts.
Paraguayan War: A Conflict That Marked South America
The presence of the ship is directly linked to the Paraguayan War (1864-1870), also known as the War of the Triple Alliance.
The conflict involved Paraguay against Brazil, Argentina, and Uruguay and is considered the largest and deadliest in South American history.
Political, territorial, and economic disputes, combined with the interest in controlling the Rio de la Plata basin, created a tense scenario that lasted more than five years.
The conflict began with clashes between Paraguay and Brazil and quickly expanded. The consequences were devastating, especially for Paraguay, permanently altering the political and territorial dynamics of the region.
It is in this context that military vessels gained a strategic role, especially in the inland waterways.
The Tamandathay and Its Destiny
The steamship Tamandathay was purchased by Emperor Dom Pedro II in 1860, with the aim of reinforcing the Empire’s fleet in defense and transportation operations during the war.
Even after the end of the conflict, the vessel continued to operate, transporting troops, authorities, and supplies through the rivers of inland Brazil.
On April 20, 1883, about six decades after its construction, the Tamandathay collided with a submerged rock while navigating the Tietê.
The impact opened a breach in the hull and water quickly flooded the interior. A boiler failure left the ship adrift until it sank. Despite the scare, all aboard survived.
Today, the remains of the Tamandathay lie about 20 meters deep, in a calm stretch of the river, away from the pollution of the metropolis.
The ruins spark curiosity and help keep alive the memory of a decisive period in Brazilian history, serving as a silent link between the past and present.
