  • Timeline


    A unique Project

    The LSC's mission is to arouse interest in science and technology among the general public and youngsters in particular. Orienting the latter towards the highly scientific professional workplace of the 21st Century is indeed a challenge faced by most OECD countries, including Luxembourg. This goal will be achieved through the excitement generated by a multitude of spectacular, interactive, recreational, and educational workstations, workshops and labs. In October of 2015, the Luxembourg Government has officially recognized this private initiative as an “Institution of National Interest”.

    Today there are more than 3,000 Science Centers in operation around the world, generally catering to youth and their family. In total, they boast 300 million visitors per year, the largest of them reaching an average of 300,000 per year. The LSC is the first institution of its kind in Luxembourg and in the Greater Region.


    From Past to Future
    The LSC will also be the anchor institution for tourism in the South of Luxembourg. The Red Rock Region in Luxembourg and its neighboring areas of France, Belgium and Germany have witnessed a unique prosperity thanks to the presence, extraction and processing of raw materials like iron ore and coal. Today, economic change in the information age has brought about a shift to human intelligence and technological skills as being the only richness allowing the region to continue to prosper and thrive. The success of converting former steel producing land into a University site at Belval is an example of this evolution. The Luxembourg Science Center will be the link between this glorious past, the present and a promising future.


    The “Luxembourg Science Center (Groussgasmaschinn)” is a not for profit private institution (Asbl) whose mission it is to develop and manage a Science Center for Luxembourg and its greater Region: France (Lorraine), Germany (the Saarland and large parts of Rhineland-Palatinate) and Belgium (the Provinces of Luxembourg and Liège).

    The institution took its roots in an earlier not for profit, the “Groussgasmaschinn” (Asbl), whose more limited objective was to preserve and restore the world’s largest combustion engine, the Groussgasmaschinn, implanted in the Gas Engine Power Plant of ArcelorMittal Differdange. This earlier project of “Industrial Energy Museum” has evolved over time into the current, dramatically more ambitious, Luxembourg Science Center project.

  • Past exhibitions


    The Luxembourg Science Center organized the exhibition:


    From september 17 to november 11, 2016
    at the Forum Geesseknäppchen in Luxembourg




    Science is done by scientists. Or is it? This exhibition explores eight remarkable stories of people who are opening up scientific research to everyone in the field of health, taking it out of professional labs and into homes, workshops and back yards.

    From measuring air pollution in London to a force measuring helmet in Luxembourg or the search for new antibiotics in Amsterdam, a growing number of ‘do-it-yourself scientists’ around the world are busy hacking, experimenting and inventing. These DIY science pioneers are challenging our ideas of who a scientist is and what science will look like in the future. Will you join the DIY science revolution?

    The LSC has adapted this traveling exhibition as part of the european project SPARKS which aims at promoting Responsible Research and Innovation (RRI) across 29 european countries and will lead 7 events based on meetings between experts and citizens (detailed program).

    Phase II, to be implemented starting at the end of the decade, was already the subject of numerous architectural design efforts.

    In May of 2014, an International Architectural Workshop brought about 30 last-year architectural students and 8 professors to the site at Differdange. They represented 6 architecture faculties (Brno, Czech Republic: VUT Brno - Florence, Italy: UdS Firenze - Nancy, France: ENSA Nancy - New York, USA: NYU New York University - Saarbrücken, Germany: Htw Saar and Seville, Spain: ETSA Sevilla). The purpose of the Workshop was to develop ideas and drawings how the two industrial buildings (the neo-classical Gas Engine Power plant and the Thermo Plant) could be used for the Science Center in a new urban development.

    These initial ideas, drawings and plans have been perfected in 2015 and 2016 by more detailed work performed at ENSA Nancy and UdS Firenze in a master thesis program of about 20 students.

  • Experimental stations


    The permanent exhibition of the LSC consists of about 50 hands-on fascinating experimental stations. Visitors thus plunge into the discovery of a broad range of scientific and technological phenomena. And non scientists are fascinated by their own comfort-level and ease of understanding. To further enhance comprehension, the LSC team has opted for a three level approach of communication, easily interchangeable through touch screens:
    - Purely Illustrative for kids up to 10 years of age
    - Medium level for visitors with no or minimum scientific background
    - Expert level

    Five languages are on hand: Lëtzebuergesch, French, German, English and Portuguese. And most stations are height-adjustable to allow for a comfortable body position for the user (especially young children) and unobstructed access for visitors with limited mobility.

    Our first stations (out of a program of 100) refer to popular experimentations in fundamental and applied sciences: electricity (including one of the largest Tesla coils in the world, electro-magnetism, electronics), mechanics (statics, gravity, fluids, building and construction, resistance of materials, simple machines), combustion engines, robotics, and maths. Biology chemistry, astronomy, acoustics, and other engineering topics will follow.

    All these realizations are produced and tested within our own workshops on the industrial site of ArcelorMittal in Differdange.


  • Workshops/Shows


    For each visit, professional science mediators offer two kinds of 1-2h long activities in designated lab areas (within or outside the permanent exhibition) to enhance specific interest in selected subject matters:

    - on the one hand, spectacular and interactive demonstrations to inspire and stir curiosity;

    - on the other hand, DYI activities through guided workshops to generate self-confidence and engagement.

    The different mediation spaces give a panoramic view of sciences and technologies. They include a kitchen lab, a shop to shape materials, electricity and magnetism stages, a mechanics zone and experimentation rooms with the following themes : computer science & robotics, space sciences, thermodynamics, fluid mechanics, chemistry, biotechnology, optics, acoustics, and mathematics.


  • Groussgasmaschinn


    The preservation and restoration of the “Groussgasmschinn”, the largest combustion engine ever built in the world was the starting point of our journey. This engine was the final most successful evolution of 13 gas engines driving generators producing electrical power by using blast furnace gas (a waste product) covering the needs of the steel mill and a large portion of the country. At the end of the 19th century, the innovative idea of management at the Differdange mill, to replace steam engines through gas combustion engines should revolutionize world steel production for half a century.

    In Phase II of the project which will include the industrial heritage and technological evolution of the past, the LSC will be a benchmark of industrial heritage preservation in the purposeful way of its original use. A collection of historic large power producing engines, in operating mode will permit the visitor to experience the symbiosis between past, present and future technologies.




  • The Team


    The current team consists of about forty full-time employees. But, all in all, a hundred people have already been involved in the development of the Science Center.

    The social dimension is an important element especially concerning our human resources, because the reinstatement of the former steel workers of Schifflange, Bettembourg and Rodange, the members of the Cell of Redeployment (CDR) of ArcelorMittal, was at the root of the project. The exceptional know-how of this team and its incomparable motivation are essential both for the works of conception and construction of the experimental stations of the Science Center as well as for the works of dismantling, restoration and refurnishing of the historic equipment.


  • Our Know how


    Our know-how and experience spans all the way from the restoration, maintenance and operation of historic combustion engines to sophisticated science and technological mediation.


  • Our Partners


    The Science Center is recognized as a major institution, critical for future economic development, by Luxembourg's Government, the European Union, leading foundations acting in education, as well as by academia and industry.

    Our main partners are:
    The Ministry of Education
    The Ministry of Cultural Affairs
    The Ministry of Economy
    The Fonds National de la Recherche
    The Oeuvre Nationale de Secours Grande-Duchesse Charlotte
    The André & Henriette Losch Foundation
