The Khatt Shebib
This mystery wall was discovered in 1948 in Jordan. No one knows why it was built, when it was built, or who built it. For all they know, its just something that appeared. The wall runs north-northeast to south south-west and is 93 miles long. The wall is in ruins after it’s long life, but most believe it would have been 3.3 feet tall and 1.6 feet wide. It could have been built to keep out animals.
