40 Interesting Luxembourg Facts, from Schengen to the Casemates

Luxembourg is a grand duchy of 690,959 people wedged between Belgium, France and Germany, and it is the only country in the world still ruled by a grand duke. That combination of tiny and unusual is why the facts below exist: a country of 2,586 square kilometres holds a European Union capital, a UNESCO-listed fortress, the village that gave the Schengen zone its name and the first national public transport network anyone could ride for free. These 40 facts about Luxembourg are grouped into six sets, each checked against the government’s own figures, the national statistics office STATEC or the site that runs the attraction.

Luxembourg facts about the country and its rulers

Luxembourg is a constitutional monarchy whose head of state is a grand duke and whose head of government is a prime minister. The 8 facts below cover where the name came from and who holds each of those two jobs now.

1. The country is named after a castle. Siegfried, count of the Ardennes, acquired a rocky outcrop with a small fort called Lucilinburhuc, meaning “little fortress”, in 963, and the settlement that grew around it became Luxembourg.
2. Luxembourg is the world’s only remaining grand duchy. Several existed across nineteenth-century Europe, including Baden, Tuscany and Hesse, and Luxembourg is the one that still has a reigning grand duke as head of state.
3. The current head of state is Grand Duke Guillaume V. He was sworn in before the Chamber of Deputies on 3 October 2025, the same day his father signed the act of abdication at the Grand Ducal Palace.
4. Two long reigns preceded him. Grand Duke Jean reigned for 36 years from 1964 to 2000, and Grand Duke Henri for 25 years from 2000 to 2025.
5. National Day is 23 June, which is nobody’s actual birthday. It marks the sovereign’s official birthday, a date fixed in June for the weather, while Grand Duchess Charlotte, whose 45-year reign the tradition honours, was born on 23 January 1896.
6. The prime minister runs the government, not the grand duke. Luc Frieden of the Christian Social People’s Party has held the post since November 2023, leading a coalition with the Democratic Party.
7. A Luxembourgish leader set a European first in 2015. Xavier Bettel, prime minister at the time and now deputy prime minister, married his partner Gauthier Destenay that year, making him the first sitting EU head of government in a same-sex marriage.
8. The national motto is defensive rather than ambitious. “Mir wëlle bleiwe wat mir sin” translates as “We want to remain what we are”, and you will see it carved on buildings in Luxembourg City.

Luxembourg facts about the land and the people

Luxembourg is landlocked, small and unusually international, with close to half its residents holding another country’s passport. The 7 facts below cover the geography and the population.

9. Three countries share a border with Luxembourg. Belgium lies to the west and north, France to the south and Germany to the east, across an area of 2,586 km² (998 sq mi).
10. The highest point is a field. Kneiff, near Huldange in the north, reaches 560 m (1,837 ft) and is marked by a stone slab in open farmland rather than a summit.
11. The population passed 690,000 in 2026. STATEC counted 690,959 residents on 1 January 2026, up 1.3% on the year before.
12. Foreign nationals make up 46.6% of residents. The Portuguese community is the largest at 12.8% of the total population, followed by French residents at 7.1% and Italians at 3.7%.
13. Roughly 232,000 people commute in to work each day. Cross-border workers from France, Germany and Belgium fill close to half the country’s jobs, and about 54% of them live in France.
14. There are three official languages. Luxembourgish became the national language under a law passed in 1984, while French and German remain the languages of administration, legislation and the courts.
15. Schoolchildren learn to read in German and switch languages as they go. Primary literacy is taught in German, French is added during primary school, and English comes later in secondary education, which is how most residents end up trilingual.

Luxembourg facts about its place in Europe

Luxembourg is a founding member of both NATO and the European Union, and its capital is one of the EU’s three working seats. The 6 facts below cover that role.

16. Luxembourg was one of NATO’s 12 founding members. It signed the North Atlantic Treaty in Washington in 1949 alongside Belgium, France, the Netherlands and eight others.
17. It was one of the six countries that started the EU. Luxembourg joined Belgium, France, Germany, Italy and the Netherlands in the European Coal and Steel Community, the body that grew into today’s union.
18. Luxembourg City is an EU capital, not just a member’s capital. The Court of Justice of the European Union, the European Court of Auditors, the European Investment Bank and the Secretariat of the European Parliament are all based on the Kirchberg plateau.
19. The Schengen zone is named after a Luxembourgish wine village. Five countries signed the original agreement on 14 June 1985 aboard the boat Princesse Marie-Astrid, moored on the Moselle at Schengen, at the point where Luxembourg, France and Germany meet. The renovated Schengen museum reopened in June 2025, with the boat itself now part of the display.
20. The capital’s old quarters have been a UNESCO World Heritage Site since 1994. The listing covers the fortifications and the old town, the remains of a fortress so heavily built that it was nicknamed the Gibraltar of the North.
21. Luxembourg made all public transport free on 1 March 2020. It was the first country to do so nationwide, covering buses, trams and second-class trains for residents and visitors alike, though first class on the railways still has to be paid for. Cross-border trains and coaches into Luxembourg are a separate ticket.

Luxembourg facts about landmarks and traditions

Luxembourg’s landmarks run from a tunnel network inside a cliff to a hopping procession that UNESCO lists as intangible heritage. The 8 facts below cover what you can actually visit.

22. The Bock Casemates are the remains of a 23 km tunnel system. About 17 km (10.6 mi) of the galleries carved into the Bock promontory survive, and the visitable stretch opens daily from early March to early November for €8 ($9, £7) per adult.
23. Bourscheid is the largest castle in the country. The fortress sits about 150 m (492 ft) above a loop of the Sûre, was extended in the fourteenth and fifteenth centuries with six Gothic towers, and charges €7 ($8, £6) for adults, or nothing with the LuxembourgPass.
24. Victor Hugo wrote in exile at Vianden. The French novelist stayed in the town in 1871 and the house he rented is now a museum, a short walk below the restored castle on the ridge.
25. Echternach holds a hopping procession every Whit Tuesday. Thousands of pilgrims move through the streets in a stepping dance in honour of Saint Willibrord, a tradition UNESCO added to its Representative List of the Intangible Cultural Heritage of Humanity in 2010.
26. The Octave is the country’s biggest religious event. The pilgrimage in honour of Our Lady of Luxembourg runs for about two weeks in spring, from 26 April to 10 May in 2026, and fills Place Guillaume II with the Mäertchen, a food and craft market that runs alongside it.
27. Little Switzerland is a real place name. The Mullerthal region in the east is known as Little Switzerland for its sandstone gorges, moss-covered rock corridors and the 112 km (69.6 mi) Mullerthal Trail.
28. Wine grows along the Moselle. The valley’s vineyards work with nine grape varieties, including Riesling, Auxerrois, Rivaner, Pinot Gris and Elbling, on slopes facing the German bank of the river.
29. You can see a fortress, a castle and a vineyard in one day. The country measures roughly 82 km (51 mi) north to south, which is why day trips from Luxembourg City reach Vianden, Bourscheid and the Moselle without an overnight stop.

Luxembourg facts about food and drink

Luxembourgish cooking borrows from its German and French neighbours and keeps a handful of dishes of its own. The 6 facts below cover what to order.

30. The national dish is smoked pork with broad beans. Judd mat Gaardebounen pairs a brined, smoked pork collar with broad beans in a cream sauce, usually with boiled potatoes.
31. Gromperekichelcher are the national street snack. The deep-fried potato cakes mix grated potato with onion, parsley, egg and flour, and they are a fixture at markets and the Schueberfouer funfair.
32. Bouneschlupp is a green bean soup. It is thickened with potato and often served with sausage, and it appears on menus as an everyday dish rather than a tourist one.
33. Friture de la Moselle means small fried fish. Riverside restaurants along the Moselle serve the whole fish battered and fried, traditionally with a glass of local white wine.
34. Quetsch is a plum spirit. It is distilled from the small dark plums grown in the country and served as a digestif, sometimes alongside mirabelle or pear versions.
35. Crémant de Luxembourg is not a cheaper champagne. It is a sparkling wine made by the traditional bottle-fermentation method, and it has carried its own protected designation since 1991.

Luxembourg facts about money and business

Luxembourg’s economy rests on finance, steel and, more recently, satellites and space law. The 5 facts below cover the business side.

36. The GDP per head figure is real but misleading. Luxembourg is consistently among the world’s top three countries by GDP per capita, partly because roughly 232,000 cross-border workers produce output that counts in the numerator while they live, and are counted, abroad.
37. The minimum wage is among the highest in the EU. The social minimum wage for unskilled work rose to €2,771.33 ($3,219, £2,381) gross a month on 1 June 2026, and it moves automatically when an inflation index threshold is crossed.
38. Several household-name companies have their European base here. Amazon’s EU headquarters, PayPal’s European banking entity and the broadcaster RTL Group are all registered in Luxembourg. Skype was founded and headquartered here too, until Microsoft shut the service down on 5 May 2025.
39. Luxembourg wrote Europe’s first space-mining law. The Space Resources Act took effect on 1 August 2017, giving companies rights over material they extract in space, and it built on a satellite industry that began when the country backed the operator now known as SES in 1985.
40. The last blast furnace closed in 1997 and the site became a university. Steel made Luxembourg rich, and when Belval’s furnaces stopped, the 120-hectare site at Esch-sur-Alzette was rebuilt as the Cité des Sciences, home to the main campus of the University of Luxembourg since 2015. Two furnaces were left standing and one is open to visitors.

Where to go next

Luxembourg rewards a short trip better than a long one, because the distances are small and the sights are concentrated. Start with the capital, where the casemates, the UNESCO-listed old quarter and the Kirchberg institutions sit within a few kilometres of each other, then pick one castle and one stretch of river. Our guide to things to do in Luxembourg City covers the capital in detail, and the Luxembourg hub collects everything else we have written about the country.

WonderfulWanderings Pro Tips

The 4 tips below each change how you plan a visit to Luxembourg, and all four are about when a place is open or what it costs.

1. Check the casemates season before you book flights. The Bock Casemates close for winter and open daily from early March to early November, so a January city break gets the clifftop view and not the tunnels.
2. Free transport does not mean free first class. Buses, trams and second-class train travel cost nothing anywhere in the country, but a first-class seat on a CFL train still needs a ticket.
3. Time a spring trip around the Octave. The pilgrimage and the Mäertchen market run from 26 April to 10 May in 2026, which fills Place Guillaume II and pushes the regular Wednesday and Saturday market to Place de la Constitution.
4. Buy the LuxembourgPass if you plan on two castles. Bourscheid alone is €7 ($8, £6) per adult, and the pass covers it, so the maths turns in your favour quickly once you add Vianden or a museum.
