The Khatt Shebib

Discovered in 1948 by Sir Alec Kirkbride, this is an ancient wall that stretches for 93 miles in Jordan. A lot of the wall is gone, but you can see the foundations of the wall stretching across the dessert.

The wall leave a lot of unanswered questions for researchers, who are curious how old it is, and how high it once was. Given the amount of rubble nearby, it couldn’t have been high enough for defence.
