The buildings of the fictional city Mos Espa are slowly becoming buried by sand dunes migrating over the Tunisian desert. These buildings were sited on the planet Tatooine during the The Phantom Menace, "Episode I" and are the home of the young Anakin Skywalker, later to become Darth Vader.
Ralph Lorenz, from Johns Hopkins University, US, together with Jason Barnes, from the University of Idaho, and Nabil Gasmi, of the University of Sousse, Tunisia, visited the Mos Espa site in 2009, and noted that part of a nearby set used in Star Wars Episode IV: A New Hope had already been overrun.
Using satellite images of the site, they were able to determine the speed of dune movement, which is approaching the buildings once inhabited by such luminaries as Anakin, his slave owner Watto, and rival podracer Sebulba.
