6. The Nazca lines


The Nazca Lines are enormous drawings on the ground (called geoglyphs) that stretch across the Nazca desert in Southern Peru. They show more than 300 geometric patterns, spirals and animals. The lines are so vast (one extends 65 km) that they can only be seen properly from a height of about 300m.
The lines were first noticed when commercial aeroplanes began to fly over Peru in the 1920s. Most experts agree that they were made by the Nazca Indians who lived in the region between 300 B.C and 800 A.D, but there are many questions yet to be answered about them. For example, why were the pictures made and how are they so precise if their makers had no mean to view them from the sky.
