Sajama Lines, Ancient geoglyph network near Nevado Sajama, Bolivia.
The Sajama Lines are a network of straight paths crossing the high-altitude Altiplano plateau in western Bolivia. These routes were created by removing dark surface stones to reveal lighter soil underneath, forming visible markings that can be seen from above.
Indigenous communities created these paths around 3,000 years ago to connect religious sites and settlements across the high plateau. The scale of the project reveals how ancient cultures organized and managed the challenging landscape.
The network of paths contains multiple radial centers that connect to religious structures, burial towers, and settlements across the high-altitude landscape.
These paths are best viewed from elevated vantage points or through satellite imagery, as they are difficult to see from ground level. Visitors should bring sturdy footwear and sun protection, since the terrain is open and exposed to intense high-altitude sun.
Some lines radiate outward from central points in star-like patterns, suggesting they may have been connected to astronomical or ritual observations. This radial design sets them apart from other geoglyph systems found elsewhere in South America.
