The Swiss megaliths, just like the English sites, hold an obvious interest for archaeology and astronomy. Within the sites located in Switzerland, the megaliths of Corcelles–Concise have some particular characteristics which are, in our opinion, relevant to point out. Indeed, using recent astronomical software, we have been able to attribute to this site a probable astronomical function. This lead us to wonder about the general use of this kind of location, with some insights on a cultual plan.
