About this sheet

Upper & Lower Guinea Coast Map – West Africa by Bonne c.1780

DESCRIPTION
This detailed coastal map covers Upper and Lower Guinea, extending from Sierra Leone toward Central Africa. Compiled by Rigobert Bonne, it reflects European maritime priorities, showing river mouths, anchorages, and coastal settlements essential to navigation and trade. Inland detail diminishes rapidly, illustrating contemporary limits of geographic knowledge. The map documents a critical region in Atlantic trade history and remains a powerful historical reference.

FRAMING TIPS
Wide mat balances the horizontal format; muted gilt or dark wood frame recommended.
