<p style=";text-align:left;direction:ltr"><strong>Weather of Arabia -</strong> A group of archaeologists announced the discovery of about 400 mysterious <strong>stone structures</strong> in <strong>Saudi Arabia</strong> dating back thousands of years, along with a few wall-like formations.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> The stone walls, which archaeologists called the &quot;gates&quot;, were found in groups in an area located in the western center of the kingdom, called Harrat Khaybar.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> It is reported that the scientists involved in the research are not sure of the purpose behind the existence of these gates, or even their exact age.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> The researchers found that a number of the gates, discovered via satellite imagery, are located alongside a basalt dome left over from the lava.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"><br /> David Kennedy, a professor at the University of Western Australia, said the gates are made of stone and appear to be the oldest man-made structures within the landscape.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"><br /> The height of the smallest gate is about 13 meters, while the length of the largest one is 518 meters, and most of them are rectangular in shape.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"><br /> Kennedy added that thousands of years ago, the landscape was more suitable for human life. Other types of stone structures have also been discovered in lava fields.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> Most of the gates were discovered through satellite images, as no field research was conducted on them. Volcanologists said basaltic lava had previously covered some stone structures, including the gates.<br /></p>
