National Historical Museum
Latin America's largest coin collection lives inside a fort that was, at various points, a slave prison and an ammunition depot.

Founded in 1922, the museum holds over 287,000 items across more than 25 exhibits — but the building earns as much attention as the collection. The complex accumulated its layers from 1567 to 1835: Portuguese fort, Calaboose Prison for enslaved people (1693), Casa do Trem weapons depot (1762), War Arsenal (1764), Barracks (1835). The library alone holds 57,000 titles, some dating to the 15th century.
What to look for
- The numismatic collection — the largest in Latin America, drawn partly from the National Library's Numismatic Office
- The Casa do Trem, the 1762 ammunition depot where the museum first opened in October 1922
- The library's 15th-century titles alongside 50,000 documents and photographs
The complex covers 20,000 m² at Calaboose Point — allow at least two hours to work through the permanent exhibits.
