Why visit

Imbuí belongs to the Guanabara entrance’s system of fortifications protected by Iphan in 2024. Its seaward position helps explain expanding defensive lines and modernised artillery. The complex’s historical importance should not be confused with unrestricted tourist access to the fort or surrounding military land.
