A faithful, geo-referenced cartographic reconstruction of the longest road in southern Italy, as depicted on the Atlas of the Kingdom of Naples between the end of the eighteenth century and the beginning of the nineteenth century. Thanks to the extreme precision of the map, the toponymy and the numerous and detailed topographical references, it was possible to identify and position the historical layout on the modern satellite views.  These basic activities were accompanied by a careful survey of the places, interviews with local history experts, very precious sources of information, and a fundamental and fruitful archive work. Finally, the last piece, perhaps the most fascinating, concerning the testimonies of travelers who, between the eighteenth and nineteenth centuries, traveled and described the places crossed by the road. The first part of this study concerns the reconstruction of the route from Naples to Castrovillari (the first post station in the Calabrian territory). From Naples to Castrovillari the road covers the distance of 143 Neapolitan miles. The "story" is divided into chapters, each chapter coinciding with a section of the postal itinerary of the late eighteenth century. From Naples to Castrovillari there are 14 postal routes, each of which covers an average length of 10 miles, corresponding to the distance that a galloping horse could travel without stopping.  Castelluccio Inferiore housed the twelfth Post Station, starting from Naples. This work aims to serve as a starting point to provide a homogeneous key to the history of a road that unites different realities, but positioned along the same line traveled by men for centuries, hoping for a concrete initiative to enhance the places in a cultural and tourist key.
