French Guiana

The geography of the European Union describes the geographic features of the European Union (EU), a multinational polity that occupies a large portion of Europe and covers 4,225,104 km (1,631,322 sq mi). Its European territory extends northeast to Finland, northwest to Ireland, southeast to Cyprus in Asia and southwest to the Spanish exclaves on the Mediterranean shores of North Africa. Additionally, the EU includes numerous islands around the world, and French Guiana in South America.

Collectively, it represents the seventh largest territory in the world by area. Including all overseas territories, the EU shares borders with 20 countries.

France, officially the French Republic, is a country primarily located in Western Europe. Its overseas regions and territories include French Guiana in South America, Saint Pierre and Miquelon in the North Atlantic, the French West Indies, and many islands in Oceania and the Indian Ocean, giving it the largest discontiguous exclusive economic zone in the world. Metropolitan France shares borders with Belgium and Luxembourg to the north; Germany to the northeast; Switzerland to the east; Italy and Monaco to the southeast; Andorra and Spain to the south; and a maritime border with the United Kingdom to the northwest. Its metropolitan area extends from the Rhine to the Atlantic Ocean and from the Mediterranean Sea to the English Channel and the North Sea. Its 18 integral regions—five of which are overseas—span a combined area of 632,702 km (244,288 sq mi) and have an estimated total population of over 68.6 million as of January 2025. France is a semi-presidential republic. Its capital, largest city and main cultural and economic centre is Paris.

Metropolitan France was settled during the Iron Age by Celtic tribes known as Gauls before Rome annexed the area in 51 BC, leading to a distinct Gallo-Roman culture. In the Early Middle Ages, the Franks formed the kingdom of Francia, which became the heartland of the Carolingian Empire. The Treaty of Verdun of 843 partitioned the empire, with West Francia evolving into the Kingdom of France. In the High Middle Ages, France was a powerful but decentralised feudal kingdom, but from the mid-14th to the mid-15th centuries, France was plunged into a dynastic conflict with England known as the Hundred Years' War. In the 16th century French culture flourished during the French Renaissance, and a French colonial empire emerged. Internally, France was dominated by the conflict with the House of Habsburg and the French Wars of Religion between Catholics and Huguenots. France was successful in the Thirty Years' War and further increased its influence during the reign of Louis XIV.

The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about 7,000,000 km (2,700,000 sq mi), or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela, as well as the territory of French Guiana.

Most of the basin is covered by the Amazon rainforest, also known as Amazonia. With a 6 million km (2.3 million sq mi) area of dense tropical forest, it is the largest rainforest in the world.

The European Space Agency (ESA), pronounced 'ee-sah', is a 23-member international organisation devoted to space exploration. It has its headquarters in Paris and a staff of around 2,547 people globally as of 2023. ESA was founded in 1975 in the context of European integration. Its 2025 annual budget was €7.7 billion.

The ESA human spaceflight programme includes participation in the International Space Station (ISS) and collaboration with NASA on the Artemis programme, especially manufacturing of the Orion spacecraft's European Service Module (ESM). ESA launches and operates uncrewed missions to the Moon, Mars, Jupiter, Venus, Mercury, the Sun, and various comets and asteroids. Other activities include space telescopes, Earth observation satellites, asteroid impact avoidance, telecommunication and navigation satellites, designing launch vehicles (e.g. Ariane 6 is operated through Arianespace with ESA sharing in the costs), and maintaining Europe's Spaceport (the Guiana Space Centre at Kourou, French Guiana), as well as space safety and commercialisation.

The Guianas, also spelled Guyanas or Guayanas, are a geographical region in north-eastern South America. Strictly, the term refers to the three Guianas: Guyana, Suriname, and French Guiana, formerly British, Dutch, and French Guiana respectively. Broadly, it refers to the South American coast from the mouth of the Orinoco to the mouth of the Amazon.

The West Indies are an island subregion of the Americas, surrounded by the North Atlantic Ocean and the Caribbean Sea, which comprises 13 independent island countries and 18 dependencies in three archipelagos: the Greater Antilles, the Lesser Antilles, and the Lucayan Archipelago.

The subregion includes all the islands in the Antilles, in addition to The Bahamas and the Turks and Caicos Islands, which are in the North Atlantic Ocean. The term is often interchangeable with "Caribbean", although the latter may also include coastal regions of Central and South American mainland nations, including Mexico, Belize, Honduras, Panama, Colombia, Venezuela, French Guiana, Guyana, and Suriname, as well as the Atlantic island nation of Bermuda, all of which are culturally related but geographically distinct from the three main island groups.

Suriname, officially the Republic of Suriname, is a country in northern South America, also considered as part of the Caribbean and the West Indies. Situated slightly north of the equator, over 90% of its territory is covered by rainforest, the highest proportion of forest cover in the world. Suriname is bordered by the Atlantic Ocean to the north, French Guiana to the east, Guyana to the west, and Brazil to the south. It is the smallest country in South America by both population and territory, with around 612,985 inhabitants in 2021 in an area of approximately 163,820 square kilometers (63,251 square miles). The capital and largest city is Paramaribo, which is home to roughly half the population.

Suriname was inhabited as early as the fourth millennium BC by various indigenous peoples, including the Arawaks, Caribs, and Wayana. Europeans arrived and contested the area in the 16th century, with the Dutch controlling much of the country's current territory by the late 17th century. Under Dutch rule, Suriname was a lucrative plantation colony focused mostly on sugar; its economy was driven by African slave labour until the abolition of slavery in 1863. Approximately 300,000 enslaved Africans were taken to Suriname during the transatlantic slave trade, from the mid-1600s to the early 1800s. After 1863, indentured servants were recruited mostly from British India and the Dutch East Indies. In 1954, Suriname became a constituent country of the Kingdom of the Netherlands. On 25 November 1975, it became independent following negotiations with the Dutch government. Suriname continues to maintain close diplomatic, economic, and cultural ties with the Netherlands.

Fort Cépérou was a fort that protected the city of Cayenne, French Guiana. It is named after Cépérou, a celebrated indigenous chief who ceded the land.

The original wooden fort was built on a hill looking over the mouth of the Cayenne River in 1643. Over the years that followed the French temporarily lost the site to the Dutch, English and Portuguese. The fort was torn down and rebuilt several times.

Cayenne (/keɪˈɛn/; French pronunciation: [kajɛn] ; Guianese Creole French: Kayenn) is the prefecture and capital city of French Guiana, an overseas region and department of France located in South America. The city stands on a former island at the mouth of the Cayenne River on the Atlantic coast. The city's motto is "fert aurum industria", which means "work brings wealth". Cayenne is the largest Francophone city of the South American continent.

In the 2021 census, there were 151,103 inhabitants in the metropolitan area of Cayenne (as defined by INSEE), 63,468 of whom lived in the city (commune) of Cayenne proper.
