During the era of the great European overseas empires, the NE coast of South America had a string of “Guianas” [click on map to enlarge]: Spanish, British, Dutch, French, and Portuguese.
The Spanish colony is now part of Venezuela; the British is Guyana (capital is Georgetown); Dutch is Suriname; next is French Guiana; and the Portuguese colony is part of Brazil.
Guyana and Suriname are both sovereign states. French Guiana (the least populous of the trio: less than a quarter million) remains an overseas region of France -- and also, since 1968, has acted as its spaceport, being close to the equator and the ocean.
[Until the 1950s it had also been famous for 'Ile du Diable' -- Devil's Island -- which housed political prisoners].
