Kouilou Coastal Culture Festival in Loango/Pointe-Noire coast
The Kouilou coast around Loango, once the seat of the pre-colonial Loango Kingdom and now Pointe-Noire's southern shoreline, is listed here as host to a coastal culture festival, but the cited source is the same Brazzaville traditional-music festival website flagged elsewhere as a low-match reference, so specifics beyond the region's real Vili and fishing-community heritage remain unconfirmed.
Long before Pointe-Noire existed as a colonial port city, the Loango Kingdom ruled this stretch of Atlantic coast from roughly the 1550s to the 1880s.
