Archaeologists in Peru have found that the Caral civilization of ancient Peru, from 5,000 years ago, used astronomical calculations to build its most important structures. They studied 55 structures at 10 sites and found three orientations. “One toward the so-called major lunar standstill (when the moon’s range of declination reaches a maximum) and another toward sunrise in the summer solstice, which in the Southern Hemisphere occurs in December.”
“A third, weaker orientation was toward the rising of Sirius, the brightest star at night in the Southern Hemisphere.”
“It is not by chance that during every summer solstice the first rays of the sun enter through the stairs of the Caral Archaeological Site’s central pyramid and traverse its main hall through its niches. It’s very likely that a person had been on top of the buildings as the main point of observation to monitor both sunrises and sunsets, in the case of the solstices,”
The summer solstice is the start of the harvest period. The lunar standoff though only occurs every 18.6 years.
The Caral inhabitants built an underground observatory for the person to work at night under a covered area.
