Australian “Stonehenge” May be The Oldest Observatory in The World


Archaeologists studying on a group of rocks that line up with the sun during the solstices and equinoxes. They assume that this is the world’s oldest astronomical observatory. The stones located in Australia, are particularly notable because archaeologists have recently recognized that the indigenous people of this region built permanent dwellings and farmed, and were not nomadic gatherers, as previously thought.

Ancient stone buildings

The Stonehenge is one of the most famous archaeological site in the world. Many of these buildings were built by different ancient peoples, to track the movement of the sun and moon. With their help, the ancients learned about the change of seasons and often they used these sites for religious ceremonies.
Nevertheless, the search for the oldest observatory may have been led in the wrong place. The researchers focused on Europe and the Middle East, but the oldest building was built 7000 years ago. But the age of hundreds of basalt stones, located to the west of Melbourne (Australia), still has not been precisely defined.

Australian Observatory

Dr. Duane Hamasher from Monash University, who specializes in astronomical knowledge of indigenous peoples of Australia, says that the surrounding structures are aged 11-14 thousands of years, and the observatory can also be dated to the same period. The construction combines stones, located on the “egg-shaped” curve. Two stones groups form straight lines which are interconnected. Together, they coincide with the position of the setting sun during the solstices and equinoxes.


Traditional knowledge about how to use the observatory, and perhaps even the very fact of its existence, were lost when the indigenous people of this region have been killed or relocated during the 19th century. The existence of this stone structure was known only in the 1970s. Nevertheless, an observatory forgotten again, and scientists interested in it just now, when they were rediscovered by new documents that are relevant to this area. Dr. Hamasher hopes to find this place “treasury”. He published an article on this stone structure four years ago, but the recent discovery of remains of buildings and agriculture is almost next to the observatory again revived interest in it.

Is it possible to determine the age of buildings

According to Dr. Duane Hamasher, the age of these stones can be determined either by means of thermoluminescence, which may show how long the soil has been protected from the impact of cosmic rays, or with the help of organic matter, if they can be found under stones.

The unique structure remains nameless

Researchers call the observatory Woerden Yang, but in fact this name belongs to the highest hill in the region. The original name, which was given to the construction of the indigenous peoples, are now known. The exact location of the observatory are also kept secret to prevent vandalism. On the territory of Western Victoria, a large part of evidence of the existence of a permanent architecture of continental Australia. In particular there have been found difficult to trap eels, whose age – 8000 years. It is still unknown whether the observatory is unique in its kind, or have similar structures, which have not yet been found. Many other stone structures can be found throughout Victoria, but the observatory is unique.
