The horse trail has been named for Saint Jacopo, the patron saint of Pistoia since the 12th century, that is, since his relics were brought there from Galicia thanks to the initiative of the Bishop Atto. This act established Pistoia as a pilgrimage destination. The itinerary, beyond interesting historical, cultural and nature sites, covers important scientific stops like Pratorsi, the site of a famous observatory. The horse trail is about 260km long and is made up of 12 sections of varying lengths and difficulties. Sections which include sites of historical importance, villages and view points. Amongst these should be noted Vinci, the birth place of Leonardo Da Vinci; Carmignano and its wines; Comeana and the Medici villa at Artimino.
