Espaço Cultural da Marinha, Naval museum at Orla Conde, Rio de Janeiro, Brazil

The Espaço Cultural da Marinha is a museum in downtown Rio de Janeiro that displays ships, maritime artifacts, and naval equipment across open galleries near the waterfront. It occupies the former customs docks between two historic squares.

The museum opened in 1996 on the site of former customs docks built on land reclaimed from Guanabara Bay during the 1800s. This transformation of the waterfront was part of Rio's modernization efforts during that period.

The name honors the Galeota D. João VI, a 1808 launch built in Salvador that carried the Portuguese royal family on Guanabara Bay outings. The Riachuelo submarine, built in 1973, logged over 181,000 nautical miles before decommissioning. The Laurindo Pitta tug, built in 1910, served in the DNOG squadron and fought at the Battle of Toninhas in 1918.

Boats to Ilha Fiscal and to the entrance of Guanabara Bay leave from the museum daily, so check departure times on arrival before touring the exhibits. The exhibition area covers about 1,100 m² on the Orla Conde between Largo da Candelária and Praça XV, with the submarine Riachuelo and the other vessels displayed outdoors.

Daily boat trips to Ilha Fiscal depart from here, offering views of multiple sites along Guanabara Bay that tell different parts of Rio's naval history. Few visitors know this option exists when they first arrive.
