Rasanga

Rasanga was a riverside village in the country of Mananghare on Madagascar's southeastern coast. The traveller Leguével de Lacombe described reaching it by canoe after following the river southwest from its mouth. Farther upstream stood Fifahoumé, the principal village of the district, on a mountain crest. The river linked the coastal settlements with the inland seat of a local chief, Razouma, whose country the traveller described as fertile.

The later city of Farafangana lies here.
