Cambongo Dam / Sassa Reservoir

The Cambongo River, also known in its final stretch as the Negunza River, preserves along its course a unique history for Sumbe and Angola. Along its waters stands the former Sassa weir, a structure that once powered a small hydroelectric plant. It was precisely with the energy produced by the Cambongo that Novo Redondo, today Sumbe, entered history as the first city in Angola to benefit from domestic electric lighting, a pioneering milestone that remains part of the local memory to this day.
A few kilometres away, approximately 6 km to the east, lie the impressive Sassa Caves, karst formations connected to the same hydrogeological system as the river.
