So who made the tracks and how old are they? It’s hard to tell. Some tracks act like service roads, acknowledging ancient building by running right up to or around them. (Some tracks seem to lead to prehistoric villages and caves, Bronze-age fortresses, and Roman villas.) This might mean that the roads and structures are the same age. In other cases, like this Punic Tomb (Phoenician, 7th – 2nd centuries B.C.), a building gets plopped down right on top of a set of tracks, obliterating or interrupting them, so that the path continues on the other side. This might tell us that the track is older than the structure. Truth is, probably many cultures helped create different sets of tracks over time.
