Identity
A fortress, a gorge city and a European crossroads
Luxembourg City is the capital of the Grand Duchy and the country's largest commune, yet it remains a small place: around 137,000 inhabitants spread over roughly 52 km2, with about 160 nationalities living side by side. Foreigners make up roughly 70 % of residents, which explains why the city feels so international. It is the seat of the government and, mostly on the Kirchberg plateau, of several European institutions: the Court of Justice, the Court of Auditors and the European Investment Bank. The Council of the EU also meets here in April, June and October.
The story starts in 963, when Siegfried, Count of the Ardennes, acquired the site of the Lucilinburhuc castle on the Bock rock through a land exchange with the abbey of Saint Maximin of Trier. That moment is treated as the birth of both the city and the country. Legend adds his wife Melusina, who is said to have vanished into the Alzette after he saw her fish tail. The Burgundians took the place in 1443, then Spanish, French, Austrian and Prussian rulers each strengthened the fortress in turn, Vauban himself having worked here under Louis XIV. The nickname that stuck was the "Gibraltar of the North". After the Treaty of London in 1867 confirmed independence and neutrality, the walls were dismantled between 1867 and 1883, but enough survives that the old quarters and fortifications were inscribed on the UNESCO World Heritage list in 1994.
What makes the capital unusual today is its landscape. The city is built on several levels around two rivers, the Alzette and the Pétrusse, which carved gorges roughly 70 m deep. Bridges such as the Adolphe Bridge and the Grand Duchess Charlotte Bridge link the upper town with the station district and Kirchberg. On top of that, Luxembourg City has also been named European Capital of Culture twice, in 1995 and in 2007 together with Sibiu in Romania.
What to see
The Old Quarters, the Bock Casemates and the Grand Ducal Palace
The UNESCO-listed old town gathers the Grand Ducal Palace, the Gothic Revival Notre-Dame Cathedral, Place Guillaume II, Place d'Armes and the Gëlle Fra war memorial, all within a few minutes' walk. Beneath it lies the heart of the fortress: the Bock Casemates, underground galleries from the Spanish and Austrian periods, entered from the Montée de Clausen. The visit is limited to a maximum of 45 minutes, the last admission depends on the season (later in July and August, much earlier from early November to late March), and the site is closed on 25 December and 1 January. The Castle Bridge, built by the Austrians in 1735, leads out towards the Corniche. Other fortification sites are worth a stop if you have time: the Pétrusse Casemates, the Holy Ghost Citadel, the Wenzel wall, Fort Thüngen and the Three Towers.
The city also has a serious cultural offer. Mudam covers modern art, the City History Museum and Villa Vauban the past and the fine arts, Casino Luxembourg and Am Tunnel contemporary creation, and the National Museum of Natural History completes the list. The Philharmonie concert hall and the Grand Théâtre handle music and stage. Opening hours and ticket prices change, so check each venue's website before you plan a day around one. Away from the centre, the Luxembourg American Cemetery in Hamm commemorates the Second World War.
Don't miss
The Chemin de la Corniche, the Grund and the gorges
The Chemin de la Corniche is attributed to the writer Batty Weber as "Europe's most beautiful balcony", and the nickname is easy to understand once you stand on it: the old ramparts overlook the Alzette valley and the rooftops of the Grund below. The Bock promontory itself rises 45 m above the Alzette and offers a 360-degree view. Down in the valley, the Grund, Clausen and Pfaffenthal quarters sit along the river, with the former abbey of Neimënster in the Grund. The Grund and Clausen are natural places to end a day on foot, with the river beside you and the fortifications above.
Because the city is built on several levels, getting up and down is part of the experience. Public lifts connect the upper town with the Grund and with Pfaffenthal, and the city's only funicular climbs to the Kirchberg plateau. The city is compact and easily walkable, but it is also hilly, so comfortable shoes matter more than a map. In autumn, the colours over the Pétrusse valley are one of the best sights of the year.
Food and drink
Hearty national dishes and Moselle wines
Luxembourgish cooking is hearty and sits between its French and German neighbours. The city advertises a handful of Michelin-starred tables for a more formal dinner (that figure is dated, so check before you book).
| Speciality | Description |
|---|---|
| Judd mat Gaardebounen | The national dish: smoked pork collar served with broad beans, a plate to try at least once. |
| Bouneschlupp | A green bean soup, one of the best-known traditional dishes. |
| Gromperekichelcher | Potato fritters. |
| Rieslingspaschtéit | A pâté made with Riesling, a regional speciality. |
| Träipen | Black pudding. |
| Kachkéis | A soft cheese spread, served as a starter or a snack. |
| Forelle in Rieslingsauce | Trout cooked in a Riesling sauce. |
| Quetschentaart | Plum tart, a traditional dessert. |
| Moselle wines and beer | Riesling, Pinot gris and Crémant de Luxembourg from the Moselle, plus local beers such as Diekirch. |
Getting around
Free public transport and day trips beyond the capital
Public transport is free across the whole country since 2020, and that covers tourists as well as residents: trains, buses and the tram. It means that, once you have landed, you can reach most of the sights without buying a ticket. The central station is about ten minutes on foot from the centre, with direct links to Paris by TGV and to Strasbourg, Metz, Trier, Cologne, Brussels, Liège and Basel. The Veloh bike-share scheme is another option.
Outside the capital, the tourist board points visitors towards three regions: the Mullerthal, the Moselle and the Éislek. The Moselle, on the German border, is the wine country behind the Riesling and the Crémant on your plate. Across the border, Trier is only 48 km away by road and Metz 60 km, which makes both easy additions for a longer trip, while Strasbourg lies 222 km away, Frankfurt 275 km and Paris 370 km. For the Mullerthal and the Éislek, travel times from the capital were not verified, so check them before you plan the day.

Good to know
A compact city, a high cost of living
The country has three everyday languages, Luxembourgish, French and German, and the euro is the currency. Luxembourg City is among the more expensive places in Europe for accommodation and eating out, and it is better to plan for that from the start than to be surprised on the spot. We have no reliable budget figures to quote, which is one more reason to make the flight the part you do not overpay for. Because the old town sits on a small perimeter, you can see the essentials in two days without hiring a car, and the combination of free transport and short distances keeps the other costs under control.
Luxembourg's airport
The country's only airport
Luxembourg Airport (Findel) is the only international airport in the country, about 6 km from the centre and around 10 km from the main railway station. Tram line T1 has run between the airport and the city centre since March 2025, and buses 16 and 29 run every 10 to 15 minutes; taxis are the alternative. The airport carried over 5 million passengers in 2024 and is the home hub of Luxair and Cargolux. We did not find a verified journey time into town, so allow some margin on your first trip.
