Why visit

At São José Fortress on Ilha das Cobras, the museum occupies tunnels and spaces associated with colonial defence and the Marine Corps’ history. Reopened in 2024 after refurbishment, it displays uniforms, documents and equipment. Compare this institutional narrative with civilian, Indigenous and Afro-Brazilian histories at other stops.
