Forte São Mateus
Forte São Mateus, a stronghold against pirates, was built between 1616 and 1620 to protect the lucrative brazilwood trade. You'll find it at the eastern end of Praia do Forte.
The eastward continuation of Rua das Pedras, Orla Bardot, is a delightful winding oceanfront promenade linking the two oldest and most picturesque sections of town (Armação and Ossos).
The biggest draws in Búzios are the natural setting plus the intoxicating mixture of opportunities for relaxation, nightlife, shopping and ocean sports. Cobblestoned Rua das Pedras is Búzios' main venue for shopping, dining and evening entertainment, overflowing with revelers on weekend nights.
Rio de Janeiro State
Forte Defensor Perpétuo was built in 1703 to defend against pirate raids on the gold passing through Paraty’s port, then rebuilt in 1822 upon Brazil’s independence from Portugal. It’s a 20-minute walk north of town. To get there, cross the bridge over the Rio Perequê Açu, then climb the Morro da Vila Velha, the hill past Praia do Pontal.
