Cacheu River Festival in Cacheu
The Cacheu River Festival is a locally documented music event in the historic port town of Cacheu, though independent sourcing beyond a single travel guide is limited. The setting carries weight regardless: a 1588 fort, a slave-trade memorial museum and a river still used for transport to the interior.
Cacheu sits on the river that shares its name, a waterway navigable by large vessels for close to a hundred kilometers inland and historically central to the town's role as one of the earliest European trading settlements in sub-Saharan Africa.
