Praia do Forte in Cabo Frio: History, Culture, and the Legacy of São Mateus Fort
Praia do Forte in Cabo Frio is one of the most famous postcard views in the Lakes Region, in the state of Rio de Janeiro. With approximately 7.5 kilometers of fine white sand, crystal-clear waters, and a deep blue sea, it delights residents and visitors year-round. More than a paradise-like landscape, Praia do Forte brings together an important historical landmark: São Mateus Fort, one of the oldest monuments on the Brazilian coast.
The origins of São Mateus Fort
The history of Praia do Forte is directly linked to São Mateus Fort, built in the 17th century to protect the region against foreign invasions, especially from the French, English, and Dutch, who competed for control of the Brazilian coast because of the value of brazilwood and the strategic position of the shoreline.
The first fortification was erected around 1616, shortly after the founding of the city of Cabo Frio. Over the centuries, the fort underwent expansions and renovations until it acquired the stone structure that remains preserved to this day.
Positioned on a rocky promontory at the end of the beach, São Mateus Fort offered a wide view of the sea, making it possible to spot vessels approaching the coast. Its cannons protected the entrance to the bay and ensured the safety of the local population.
Today, the monument is listed by the National Institute of Historic and Artistic Heritage (IPHAN) and represents an important symbol of Brazil’s military and colonial history.
A historic landmark by the sea
Visiting São Mateus Fort is like taking a journey into the past. Its simple architecture, built in stone and lime, preserves characteristics of Portuguese military engineering from the colonial period.
From the top of the walls, visitors enjoy one of the most beautiful views in the city, taking in:
The entire stretch of Praia do Forte;
Itajuru Canal;
Japonês Island;
The crystal-clear waters of the Atlantic;
One of the most famous sunsets in the Lakes Region.
The site has become a must-see stop for tourists, photographers, and history lovers.
