Which African capital lies on the Geba River estuary?

Which African capital lies on the Geba River estuary? Bissau does. It is the capital and largest city of Guinea-Bissau, situated along the estuary where the Geba reaches the Atlantic Ocean.

The Geba is a West African river that flows through Guinea, Senegal and Guinea-Bissau. Near Bissau, its mouth becomes a broad tidal estuary shared with the Corubal River. Strong tides and low-lying terrain define the landscape, while the waterway provides access for shipping and connects the capital with inland communities.

Bissau began as a Portuguese trading post in 1687 and later became an important colonial administrative and commercial center. Its port helped make it the country’s main gateway for trade, even though Guinea-Bissau’s coastline is dominated by intricate channels, wetlands and offshore islands.

The wording matters: Bissau is on the estuary, not simply on an unrelated coastal river. Conakry and Monrovia are also West African coastal capitals, but neither is the capital located on the Geba estuary.
