According to experts, the graves were dug out about 4.5 thousand years ago, because. during the bronze period.

The discovery was made thanks to scanning the territory of two oases - Al-Ula and Khaybar and the lands adjacent to them.

A large-scale study involved a helicopter, from which aerial photography was carried out, and satellite images were also analyzed.

According to researchers, the length of the "funeral alleys" with the tombs located along the length can be thousands of kilometers.
