Deep in equatorial South America, French Guiana (also known as "Guyane") is a department of France bordering Brazil, Suriname, and the Atlantic. It's a land where old abuts new in striking incongruity. Dense rainforests shelter centuries-old indigenous villages, while rockets zoom overhead, launched from the country's lucrative Space Centre. The capital, Cayenne, is a melting pot of French, Asian, African, and Brazilian cultures.
French Guiana is situated on the northeast coast of South America, and is bordered by Brazil to the south and the east and by Surinam to the west. The southern Serra Tumucumaque Mountains are part of the eastern frontier, whilst the rest is formed by the River Oyapock.
