evidence: French Guiana sits in the north-east corner of South America, north of Brazil, and alongside Guyana and Suriname. While Guyana and Suriname gained independence from their colonisers (the UK and the Netherlands respectively), French Guiana never has. It is classed as an overseas territory; its currency is the euro and its official language is French, although many also speak Creole. [...] French Guiana is largely covered in Amazon rainforest, with its development centred on a handful of towns hugging the coastline.
