The oldest astronomical place in the world is Nabta Playa, a set of stone circles that is 7,000 years old.
The ancient inhabitants of the African continent used this monument to record the winter and summer solstice, in addition to recording the exact date of the arrival of the monsoons (climatic phenomenon).
As reported by Astronomy, this rock calendar was occupied by ancient civilizations to understand climatic phenomena, in addition to observing how stars behaved and the influence they had on the passage of time.
Nabta Playa is a prehistoric stone megalith that has been chosen by researchers as the oldest in the world, surpassing the most famous of these structures built by ancient civilizations, Stonehenge.
Its location is in Africa, approximately 1,126 south of the Great Pyramid of Egypt Giza, and it holds the record for the first human-made structure of its kind.
Experts have named it as the oldest astronomical observatory on the planet and the reason for its construction was because those civilizations had a special cult of the stars, because they were nomads and they guided them when they moved to different places.
In the words of University of Colorado Professor Emeritus Mckim Malville, “This place was the first attempt by humans to make a serious connection to the heavens, and we believe it was the beginning of observational astronomy.”
Regarding its discovery, in 1960 Egypt was planning a project that would build a dam on the Nile River, which would have as a secondary effect the flooding of various historical places.
As a result of this situation, the United Nations Educational, Scientific and Cultural Organization (UNESCO) intervened, in order to avoid the destruction of famous ancient structures.
However, it was not until 1973 that a researcher named Eide Mariff found the Nabta Playa megaliths while on a tour of the Sahara.
At first, the expert, along with his team, believed that the find was a natural formation, but over the years they understood better that the rocks were aligned with the stars in a mysterious way.
After several years of research, in 1998 the place was established as the oldest astronomical place in the world when the research was published in the journal Nature.
In the following years, scientists have continued to carry out studies in the area, to understand how ancient civilizations could be guided through these rocks, which helped them understand the climate, care for their livestock and have a greater knowledge of the stars for those years.
