The Sajama Lines or Sajama Lines are located in the west of Bolivia and number several thousand (according to some sources even tens of thousands) of almost perfectly straight lines on earth.
Presumably, the indigenous peoples created these lines for about 3 thousand years, scraping the top layer of the soil and trampling the bottom layer tightly.
The lines cover an area of over 22 square kilometers and this stretch is 15 times larger than the famous Nazca plateau in Peru. However, the Saham lines are so poorly understood that they are mostly known to archaeologists.
Official science calls these lines the sacred "roads" that lead to the burial stone turrets "chulpas". And on special days, people walked along these paths, making pilgrimages. However, this is just one of the theories.
Each line of Saham is 1-3 meters wide and its length ranges from 1 kilometer to 10 km or even up to 20 km, while each line is surprisingly flat, as if drawn along a ruler, although there are many hills and other obstacles in their path, and in full they can only be viewed from a great height.

The first reports of these lines were received in the 1930s, but they could only be fully considered when satellite imagery became available.
After that, historians tried to find at least some stories or records of the construction of these lines from local residents, but nothing turned out.
When they managed to study several lines, they came to the conclusion that they are quite ancient and most likely created 3 thousand years ago or even earlier.
