Columns of Rajajil

The Rajajel Columns is an archaeological site of pillars carved from sandstone thought to be 6,000 years old. It is located in the Al Jawf Region in Saudi Arabia. 
Specifically situated in the suburb of Qara south of Sakakah, it consists of 50 groups of erected stone columns called Rajajil. Some of the existing columns are higher than three meters, while they are about 60 cm thick.
Etymology.
It is called "Rajajil" which means men because it looks like a man if it is seen from a distance.
Historical background.
Some historians say that the Rajajil columns may belong to a temple built in the fourth millennium BC. The site contains about 50 groups of erect stone pillars and several broken columns lying on the ground. These groups are distributed in a large circle overlooking a wide sandy plain. Each group includes two to ten columns; one of which is approximately three meters high. Archaeologists say that archaeological assumptions believe that the site dates back to the fourth millennium BC, and the site needs to carry out various excavations to find its secrets and mysteries. These columns are very similar to Stonehenge in Britain, which dates back to the third millennium BC. 
Perhaps this site is a complex of different temples, each group of columns link to a people or a tribe. Therefore, it is believed that the site was a religious center where human groups from outside the region visit to perform religious rituals.
Domat Al-Jandal Museum document.
A document found in the Dumat al-Jandal Museum indicates that the stone form of the columns may be related to ritual beliefs most of the time, or it is like one of the inferential forms of astronomy. The document indicates that the economic situation of the interior regions in the Arabian Peninsula, which are areas located to The south of the desert of Nafud remained, seemed unchanged until about the second millennium B.C. and represented in the practice of grazing livestock from goats, cows and sheep, in addition to relying on hunting and gathering food. The document adds that, in about 4000 BC, the influence of pottery and the practice of simple agriculture, hunting and grazing came to the north of the Arabian Peninsula. This civilization was established in the north of the Arabian Peninsula to form part of a broader civilization that extended during the fourth millennium BC Sinai, eastern Jordan, southern Syria, and western Iraq. It was called a metallic Stone Age civilization due to its discovery of the copper smelting method. This civilization is distinguished by the stone circles villages that may have been used for seasonal housing. The document refers to the site of Rajajeel by saying, "There is an exciting complex of stones and rubble near Sakakah is known as the Rajajil Columns and was an important center. It has similars in the Sinai."
The Antiquities of the Rajajel columns.
Through the efforts of the General Administration of Antiquities and Museums, many archaeological sensors were discovered through excavation at the site of the Rajajil columns in 1396 AH-1397 AH (1975-1976). Also, man-made stone tools such as scrapers, broths, blades, and a small number of pottery pieces were discovered. These findings indicate the date of the site that dates back to the copper age in the fourth millennium BC.  There is similarity between Stonehenge in Britain and these Rajajeel Columns in Sakakah that date back to the third and second millennium BC. There are similarities between the columns of Rajajil in Al-Jawf, and between the patterns of stone circles found in Al-Qassim specifically located in the south of Shoaib Al-Atashan near the center of Hanizal in the north Buraidah.
