The ghosts of two Mexican heroes, Pancho Villa and Father Miguel Hidalgo seem to haunt the streets of Chihuahua. Set among rugged hills in a semidesert landscape, it owes its foundation to the rich veins of silver discovered nearby in the colonial period. The city’s aqueduct dates from that era. This is also the starting point of the Chihuahua-Pacifico train, which crosses Copper Canyon.
