Forte de São Mateus do Cabo Frio

Forte de São Mateus do Cabo Frio sits on an elevated position overlooking Cabo Frio bay and the Atlantic coast. The structure features thick stone walls, angled bastions, and interior chambers that reveal its purpose as a military installation.

The fortress was built in the late 1500s to defend the coast against pirate raids and foreign threats. Over the centuries, it was rebuilt and adapted several times to meet changing military needs.

The fortress demonstrates how the Portuguese asserted control over the Brazilian coast and the military architectural styles they introduced. Visitors can see how the cannon placements and defensive layouts reflected this strategic approach.

The fortress sits on a hillside by the water and is reachable by a short walk from central Cabo Frio. The path is straightforward and level, and visiting in early morning or late afternoon avoids the midday heat.

The cannons inside the fortress are positioned exactly as they were during colonial times, aimed directly at the entrance to the bay. This arrangement shows how defenders controlled every ship attempting to enter the harbor.
