Two colonial maps (1611) are analyzed here, which provide information regarding geographic features, European land ownership, indigenous settlements and existing roadways in the northern area of the Mapocho valley. One of these maps depicts the layout of two parallel paths called "camino antiguo del Inga" and "otro camino del Inga" ('Inca's ancient road' and 'another Inca road', respectively). By means of field surveys (2014), and the use of colonial documentation and historical cartography, it has been possible to identify a large section of the roads' original tracings, including a gis cartographic reconstruction of the colonial and Inca roads.
