The star-shaped São João Fort is one of a string of defensive structures along the city’s waterfront. The fort comprises four redoubts (São Martinho, São Theodosius, São José, São Diogo), and is currently home to the Physical Training Center of the Army. Today, the São João Fort is open to visitors on a limited basis, and tours led by its soldier guides cover its historic architecture and weapons, and small museum. Many Rio de Janeiro boat tours pass by the fort.
Owing to its historic architecture, the São João Fort is not accessible to wheelchair users or those with limited mobility.
If visiting on a hot day, be sure to bring lots of water, sunscreen, and protective layers with you.
Wear sturdy shoes to the fort to best navigate its slopes, cobblestones, and other uneven surfaces.
Soldier-led tours are free to attend but must be reserved with the fort in advance.
The São João Fort is on Al. Floriano Peixoto in Rio de Janeiro’s Urca neighborhood. The nearest Metrô station is Botafogo—a 15-minute taxi ride away—and the area is also served by numerous bus lines. Alternatively, taxis and rideshare services offer an easy way to get around.
The São João Fort has limited opening hours that can vary through the week and typically conducts tours in the morning and in the evening. Even if you don’t have a tour booked, the landmark’s exterior can be admired on a neighborhood walk or boat tour—aim for a good weather day to see it at its best.
The São João Fort isn’t the only historic defensive structure guarding Rio’s waterfront. There are several others worth exploring, including the Forte do Leme (also known as the Forte Duque de Caxias); the Forte de Copacabana; the Forte Tamandaré da Laje; and, across the water in Niterói, the Fortaleza de Santa Cruz da Barra.
