The Khatt Shebib is an ancient wall in Southern Jordan. The remains of the wall are 150 km long, making it the longest linear archaeological site in Jordan. The archaeological ruins were first identified by British diplomat Sir Alec Kirkbride in 1948. Ever since, a range of disciplines, including archaeologists, scientists and anthropologists, have studied the wall. The date of the Khatt Shebib's construction is still unknown, however, it has been widely debated by archaeologists. This is evident as some archaeologists argue that the wall was built in the Iron Age, whilst others argue it was constructed in the Nabataean period.
