Macapa, Brazil

On the north channel of the Amazon, at the river’s broad mouth, Macapá sits smack on the Equator, cut off from the rest of Brazil. The Marco Zero monument is a place where you can hop from the Northern Hemisphere to the Southern. San Jose de Macapá Fortress, which supposedly guarded against riverine invasions, is an historic site, in a rather subdued way. Apa do Curiaú is a village of descendants of escaped slaves, with some unique local customs and commemorations. The Casa de Artesão sells handcrafts from the area’s indigenous tribes, as well as balatas, unusual ceramics covered in rubber.
