A Time Travel

In Tucuman itself and in the Calchaquies Valleys, even today, it is possible to visit the settlements of the ancient "Coyasuyo" (Southern part of "Taiwantisuyo"or Inca Empire). These places or early basements, in some cases, have been rescued and most of them are almost classified.
The Fortification-Temple known as the "Ancient Quilmes" is among the places mentioned above. La Ciudacita, another settlement is, without doubt, the most fascinating place because of its characteristics. This last site used to be a physics-astronomical observatory, so it keeps, among many other things an "Inti-Huatana" or trick to the sun, which marks the exact moment of the solscitios. This Inti-Huatana is situated over more than 4,000 mts, over the level of the sea, in an almost inaccesible place to where you arrive after 3 or more days of trekking. Near this archeological spot, the traffic of the Inca Road is much more intense because of the original pavement it used to have and that still remains. This very road was used by Los Curacas, warriors and messengers of the fabulous empire.

Inca Road

Approximately 20,000 km (12,000 mi) of Inca roads constituted a transportation network rivaled only by that of the Romans in the pre-industrial world. Since the Incas did not utilize the wheel, the road system did not serve vehicular traffic, only pedestrians and the llamas they used to carry cargo. Levees were constructed across swamps in many areas, steps were carved into hillsides, and bridges of several types were built across rivers and streams. Two so-called royal roads were built, by which the rulers could travel the length of the empire--one near the coast and one through the Andean highland. These roads were fed by many lateral routes. As important as the roads themselves were the administrative and service centers that were built along them. On principal roads a way station was located at the end of each day's travel so that travelers could rest and get fresh supplies. On parts of the highland road, at the Peruvian sites of Tambo Colorado in the Pisco valley and at Huanuco Viejo, near modern Huanuco, several enormous administrative centers with more than 3,000 buildings each were constructed to house the bureaucracy, state manufacturing and storage facilities, and related activities.
