LUXEMBOURG SEMINAR FAQ
Luxembourg City combines a UNESCO World Heritage site, with the medieval Grund and the Bock Casemates, the second largest financial hub in Europe, and a discreet yet refined way of life. For a company with financial, regulatory, or European stakes, the Grand Duchy naturally lends weight and meaning to an event. The capital is accessible in 2h10 from Paris by TGV and is located at the crossroads of the Greater Region. It is an institutional and prestigious destination with no real equivalent.
From Paris Gare de l'Est, allow 2h10 by direct TGV, with several departures daily; Brussels is approximately 2h15 away. Luxembourg Airport is located about ten kilometres from the centre, connected by direct bus, and the central station is right in the heart of the city. The Grand Duchy's position at the crossroads of Lorraine, Saarland, and Wallonia also facilitates arrivals from across the Greater Region. We coordinate group arrivals and transfers.
For a large convention or an institutional plenary session, Kirchberg is the ideal choice, facing the European institutions, with the Luxembourg Convention Centre for up to 2,000 people, MUDAM, and the Philharmonie. For an executive committee (CODIR) or a prestigious seminar, the medieval Grund and its charming hotels along the Alzette offer a confidential setting. For a wine-tasting experience, the Luxembourg Moselle and its crémant cellars are about twenty minutes away. We guide your choice based on your company's format and culture.
The Bock and Pétrusse Casemates, UNESCO World Heritage sites, are open to groups outside of tourist hours; a full evening privatisation requires procedures with the City of Luxembourg. We have experience with these applications and the contacts to obtain authorisations. Beyond the casemates, the Grand Duchy offers AOP crémant tasting, a rally in the old town, or a visit to the European institutions. Each activity is booked and logistically managed by us.
The Grand Duchy's heritage offers unique formats: private exploration of the 17 km of casemate galleries, a wine workshop focusing on Moselle crémant, a cultural rally between Place d'Armes and the Grund, or a team cohesion trek in the Ardennes forests. A masterclass on local specialities, judd mat gaardebounen or gromperekichelcher, completes the range. These activities easily fit between two work sessions. We manage suppliers, equipment, and timing.
Yes: the Luxembourg Ardennes offer castles, charming hotels, and lodges in the Our and Sûre valleys, 1h to 1h30 from the capital. Clervaux, Vianden, and Esch-sur-Sûre offer privatiseable settings amidst nature, ideal for a two to three-day immersive residential seminar. The Luxembourgish Little Switzerland, around Echternach and the Mullerthal Trail, adds a spectacular outdoor option. We select the estate based on your team size and objectives.
Yes: we regularly work with private banks, investment funds, and insurance companies established in Luxembourg. We understand the confidentiality and protocol requirements specific to this sector and know how to secure an executive or board event. Our teams coordinate in French, English, and German depending on the participants. Discretion and rigour are the norm for these projects.
The Grand Duchy applies a VAT rate of 17%, the lowest in Europe. However, Luxembourg remains a premium destination, boasting exceptional restaurants and hotels whose standards justify the investment for an executive event. The budget depends on the format, venue, number of participants, and chosen services. After an initial discussion, we will provide a tailored detailed quote and assist you with intra-community VAT if necessary.
We coordinate your entire event, managing cross-border logistics with Lorraine, Saarland, and Wallonia, and working with trilingual local suppliers. You will have a single point of contact for venue scouting, catering, accommodation, activities, and on-the-day coordination. The package adapts from a simple venue booking to a fully bespoke seminar. For companies operating between Paris and the Grand Duchy, we manage both sides seamlessly.
