Luxembourg is a landlocked country in Western Europe, wedged between Belgium, Germany, and France. Despite covering only about 2,586 square kilometers, one of the smallest sovereign states in the world, it is a founding member of the European Union and one of the world’s leading international financial centers, with the highest GDP per capita in the EU.

Where Is Luxembourg Located?

The Grand Duchy of Luxembourg sits at the crossroads of Western Europe, bordered by Belgium to the west and northwest, Germany to the east, and France to the south. It measures roughly 82 kilometers from north to south and 57 kilometers from east to west, with a total border length of 356 kilometers.

Geography of Luxembourg

Luxembourg divides into two natural regions. The northern third, known as the Oesling or Eislek, is a hilly extension of the Ardennes, with wooded valleys along the Our and Sauer rivers. The southern and central two thirds, called the Gutland, consists of lower plateaus and includes the Moselle valley, the rock formation region known as Mullerthal, and a former mining district nicknamed the Land of the Red Rocks. Elevation ranges from about 130 meters near Wasserbillig to 560 meters at Wilwerdange. The country is organized into 12 cantons and 100 municipalities, and roughly 85 percent of its land is farmland or forest.

A Brief History of Luxembourg

Luxembourg’s modern borders trace back to the Treaty of London of 1839, when European powers partitioned the old Duchy of Luxembourg between Belgium and the Netherlands, leaving the remaining Grand Duchy with the territory it holds today. A second Treaty of London, signed in 1867 after the Austro Prussian War, ended Prussian military occupation of Luxembourg City, led to the dismantling of its fortress, and established the country as a permanently neutral, independent state. Luxembourg kept a dynastic union with the Netherlands until 1890, when the two crowns separated and the House of Nassau Weilburg took the Luxembourg throne on its own. Its declared neutrality was violated by Germany in both World Wars, and after the second it abandoned neutrality altogether, becoming a founding member of the United Nations in 1945. Economically, the country moved from the German customs union before the First World War into a formal economic union with Belgium in 1921, and it was a founding member of the European Coal and Steel Community and, later, the European Economic Community in 1958.

Government and Economy

Luxembourg is a parliamentary representative democracy under a constitutional monarchy: a Grand Duke serves as ceremonial head of state, a prime minister heads the government, and a unicameral Chamber of Deputies of 60 elected members holds legislative power.

The country’s economy is unusually concentrated in finance. It is the second largest investment fund center in the world after the United States and the largest in Europe, with assets under management in its investment funds exceeding five thousand billion euros. More than 120 international banks from 25 countries operate there, managing roughly a thousand billion euros in assets and employing more than 60,000 people directly in the financial sector. Luxembourg holds a AAA sovereign credit rating, one of a small group of countries to do so. According to World Bank data, GDP per capita reached roughly 147,000 dollars in 2025, among the highest in the world, though annual GDP growth has slowed to under one percent amid a wider European slowdown.

Culture and People

Luxembourg has three official languages: Luxembourgish, French, and German, each used in different everyday and administrative contexts. According to the national statistics office STATEC, the resident population stood at 690,959 at the start of 2026, and foreign nationals made up 46.6 percent of residents, one of the highest shares of any country. Population growth has slowed alongside a falling fertility rate, which STATEC describes as the lowest on record at 1.23 children per woman.

What Is Luxembourg Known For?

Luxembourg is best known for two closely linked things: hosting major institutions of the European Union, and functioning as a global financial hub. Luxembourg City is one of the EU’s three official seats of government, alongside Brussels and Strasbourg, and is home to the Court of Justice of the European Union, the European Investment Bank, the European Court of Auditors, and parts of the European Commission, employing more than 14,000 EU staff. The old fortified quarter of Luxembourg City, centered on the Bock promontory overlooking the Alzette and Petrusse valleys, was inscribed as a UNESCO World Heritage Site in 1994 for its exceptional fortifications, including the Bock Casemates, a network of tunnels cut into the rock. The nearby Adolphe Bridge, completed in 1903, is another widely recognized symbol of the capital.

Why Luxembourg Matters

Luxembourg’s global importance is out of proportion to its size. As a seat of EU institutions, it plays a direct role in shaping European law and policy. As a financial center, its investment fund industry channels capital across the European market and beyond, and its regulatory decisions affect fund managers and investors far outside its own borders. Its history as a repeatedly contested, then deliberately neutral, and now firmly integrated European state also makes it a useful case study in how small countries can secure lasting stability through international institutions rather than military strength.
