Why Luxembourg City Belongs on Your Bucket List
Luxembourg City is one of Europe’s great hidden gems — a small capital with a disproportionately impressive collection of history, culture, natural beauty, and culinary excellence. A UNESCO World Heritage Site, home to European institutions, and set within a dramatic landscape of river gorges and rocky cliffs, it rewards visitors with layers of discovery that continue to reveal themselves the longer you stay.
The best way to experience Luxembourg City fully is, of course, to stay somewhere that feels like a home rather than just a room — which is exactly what Key Inn Serviced Residences offers. But first, here’s what you’ll do when you get here.
1. Walk the UNESCO Fortifications and Old Town
Luxembourg’s old town and its legendary fortifications are the city’s most iconic attraction, and rightly so. The Bock Casemates — a labyrinthine network of underground tunnels carved into the cliff face over centuries — offer a genuinely dramatic glimpse into the city’s military history. Walk the ramparts, peer down into the Alzette Valley from the Corniche (dubbed ‘the most beautiful balcony in Europe’), and wander the cobblestoned streets of the upper city, where grand ducal palaces, medieval churches, and elegant squares coexist in remarkable harmony.
2. Explore the Grund and the Alzette Valley
Below the old town’s fortifications lies the Grund — Luxembourg’s most picturesque district, tucked into the deep valley of the Alzette river. Beautifully preserved medieval buildings, a working abbey, riverside restaurants, and a network of walking paths make this one of the most charming neighbourhoods in any European city. On summer evenings, the Grund’s restaurant terraces are buzzing, and the whole area takes on a magical quality as the valley walls glow in the fading light.
3. Visit MUDAM — Luxembourg’s Museum of Modern Art
The Musée d’Art Moderne Grand-Duc Jean (MUDAM) is among Europe’s finest contemporary art museums. Set in a dramatic building designed by architect I.M. Pei, positioned over the ruins of Fort Thüngen with views across the Kirchberg plateau, it hosts world-class rotating exhibitions alongside a permanent collection that spans painting, sculpture, design, photography, and video art. The café is excellent, and the entire complex is well worth half a day.
4. Attend a Concert at the Philharmonie
Few concert experiences in Europe match the Philharmonie Luxembourg, the city’s extraordinary purpose-built concert hall. Designed by Christian de Portzamparc and completed in 2005, it hosts the Luxembourg Philharmonic Orchestra and welcomes leading international soloists and ensembles throughout the season. Even if you’re not a devoted classical music fan, a Philharmonie evening is one of those experiences that make a city visit truly memorable.
5. Cycle or Walk the Pétrusse Valley
The Pétrusse is one of Luxembourg City’s great natural secrets. This wooded river valley cuts through the heart of the city, running beneath the viaducts and cliff-top fortifications, and its network of paths offers a wonderfully peaceful escape from urban life. Walk or cycle the length of the valley and you’ll experience a side of Luxembourg City that most short-stay visitors never discover — the city at its most serene and natural.
6. Explore Parc de Merl and the Pool
For a taste of daily life in Luxembourg, spend a morning at Parc de Merl — one of the city’s most beloved green spaces and a genuine neighbourhood gathering point. In summer, the outdoor swimming pool (Piscine de Merl) is a Luxembourgish institution, filled with locals of all ages and the perfect antidote to a long day of sightseeing. It’s also, incidentally, directly beside Key Inn’s Parc de Merl apartments.
7. Take a Day Trip to the Moselle Wine Valley
Luxembourg’s Moselle Valley — running along the border with Germany — produces some remarkably good white wines, particularly Riesling, Pinot Gris, and the local sparkling Crémant de Luxembourg. The valley is an easy 30-40 minute drive from Luxembourg City, and a day trip combining wine tastings at family-run domaines with lunch in one of the riverside villages is among the most pleasurable ways to spend a free day.
8. Discover the Kirchberg Plateau
The Kirchberg plateau to the east of the city centre is home to Luxembourg’s European Quarter — the seat of the European Court of Justice, the Court of Auditors, and several other EU institutions. It’s also home to the Grand Duchy’s newest cultural cluster, including MUDAM, the Philharmonie, and the National Museum of History and Art’s newer annexe. The contrast between the grandeur of the European institutions and the remarkable natural landscape falling away into the valley below is uniquely Luxembourgish.
9. Shop and Eat on the Grand-Rue and Place d’Armes
Luxembourg’s main shopping thoroughfare, the Grand-Rue, and the elegant square of Place d’Armes form the commercial and social heart of the old town. The Grand-Rue has a good mix of international brands and local boutiques; Place d’Armes is lined with restaurant terraces that are reliably excellent in summer. The covered market at the nearby Place Guillaume II operates several days a week and is wonderful for gourmet food shopping.
10. Explore Beyond the City: Vianden, Clervaux, and the Ardennes
Luxembourg is a small country, and from the capital you can reach its most dramatic landscapes within an hour. The medieval castle of Vianden, perched above the Our river valley in the north, is one of the most romantic fortress towns in Europe. The town of Clervaux, with its Benedictine abbey and the famous Family of Man photography exhibition, is equally worth the drive. The Luxembourg Ardennes, in the north of the country, offer exceptional hiking and cycling for the active visitor.
