It is considered the first permanent military structure built by the Portuguese in Brazil.
The mortar for the masonry was composed of a mixture of sand, lime, and whale oil.
The fort was originally named Forte de São Tiago before being renamed in honor of the saint.
In 1562, the fort successfully defended the region against an attack by the Tamoyo indigenous tribe.
The surrounding Parque dos Tupiniquins contains replicas of indigenous dwellings to illustrate local history.
It is listed as a national historical heritage site by IPHAN, Brazil’s federal heritage agency.

Forte São João is the oldest fortress in Brazil, commissioned in 1532 and completed in 1547 to defend the southern coast against European invaders. It is built from stone and whale oil, a common colonial construction technique in the region. The interior houses an exhibition detailing the history of the Tupi indigenous people and the arrival of the Portuguese. The fort served as a key strategic point during the early colonial settlement of the São Vicente captaincy. Its location at the mouth of the Itapanhaú River provided a clear vantage point for monitoring maritime traffic. The fortress is surrounded by the Parque dos Tupiniquins, an outdoor area featuring native vegetation and historical statues. It remains an essential site for understanding early Brazilian military architecture and indigenous interaction.
