Cayenne

Cayenne occupies part of a former island at the mouth of the Cayenne River, where the water meets the Atlantic coast of Guiana. Spanish explorers visited the surrounding coast but judged the heat too severe for settlement. France made the first attempt in 1604, only for the Portuguese to destroy the new establishment while asserting their territorial claim. Colonists returned in 1643 and laid out Cayenne, but attacks by Indigenous inhabitants forced them to withdraw once more. France finally established a settlement that endured in 1664.

The early town remained vulnerable to imperial rivalry. Over the following decade it passed among French, Dutch and English hands before returning to France. The nearby sea and river gave the place strategic value, but heat, local resistance and competition made control uncertain. Cayenne's name marks a contested coastal foothold whose importance grew from its maritime access.
