Itaipu Fortress

Itaipu Fortress is a military installation in Praia Grande along the Brazilian Atlantic coast, built with walls, gun emplacements, and barracks. The buildings and fortifications follow a clear strategic layout to watch over the coastal waters.

The fortress was built in 1903 to protect the Brazilian coast from sea-based attacks. It was one of several defense installations constructed along the coast during this period.

The fortress was part of Brazil's coastal defense system and shows how the country wanted to protect its waters in the early 1900s. You can still see today the building style and layout that were typical of this defense strategy.

The grounds are open daily and offer clear views of the surroundings and the chance to explore different parts of the installation. Sturdy shoes are a good idea since the terrain can be uneven and some areas have steps or rises.

The fort sits in an exposed position jutting toward the water, giving a rare viewpoint over the harbor bays. This particular location is one of the few places where you can understand the defense logic of the 1900s from such close quarters.
