The new visitor centre for INFN’s National Laboratories of the South (LNS) was inaugurated on 27 July. It is a space where the INFN-led scientific endeavours, including those in which LNS participate, are recounted in an interactive, multimedia fashion. It is a place for welcoming the public, a space that is to be made available, in particular, for the city of Catania and the Sicilian Region for the development of cultural itineraries that also explore the historical collaboration with INFN. The visitor centre is a multimedia centre of 400 m2 incorporating an itinerary of interactive exhibits and installations. Here, the visitor will be able to delve into a history of science ranging from nuclear physics to astroparticle physics, from particle accelerators to interdisciplinary research, and which includes important repercussions in the field of cultural goods and medicine. These are all activities in which LNS is a protagonist on the international stage. Thanks to this new piece of infrastructure, the Laboratories of the South will present citizens with an evocative narrative of research, technological developments, and the economic and social repercussions of the basic research activities that they lead, beginning in Sicily, and thanks also to the support of the Region.
