Fortaleza de São José de Macapá
The top man-made attraction in Macapá also happens to be Brazil's largest fort. Completed in 1782 after 18 grueling years, Fortaleza de São José de Macapá is constructed of stones brought from Portugal as ship ballast. The well-preserved buildings house a visitor center, an art gallery, a meeting room, and a dance-music recital room.
