The Inca road system was the most extensive and advanced transportation system in pre-Columbian South America. It was about 39,900 kilometres (24,800 mi) long. The network was based on two north-south roads with numerous branches.The best known portion of the road system is the Inca Trail to Machu Picchu. During the Spanish colonial era, parts of the road system were given the status of Camino Real.  In 2014 the road system became a UNESCO Wolrd Heritage Site. The Qhapaq Ñam project aims to organise workshops with various communities living around the great Inca Trail, especially in the Vilcashuaman-Pisco region in Peru. The goal of these workshops is to contribute to the capacity-building of the local people in relation to cultural heritage, and alternative ways of managing patrimonial resources. For example, capacity building programmes were developed for women about handicrafts production, thus fostering their participation in cultural processes.
