Scattered across Jordan, 12 giant ring structures, which can be fully visible only in images taken from an airplane or satellite, have puzzled scientists.
Jordan has an archaeological secret – Big circles. These huge structures are made of stone walls with a height of only 1-1.5 meters, and a circumference of about 400 meters.
They were first discovered in the 1920s, but more recently, when aerial photography was widespread, scientists began to show interest in these obscure structures. There were no holes in the circles, so people had to jump over low stone walls to get inside.
Even today, experts still do not know when the circles were built, who built them or why this was done. However, based on artifacts discovered near these structures, archaeologists have suggested that they were built at least 2000 years ago. Other experts have suggested that circles can even be much older.
