Happy Star Wars Day! To celebrate, we’re at the Tunisian salt pan called Chott el Djerid. Nearby is a town called Matmata, where the residents still live and work in below-ground cave dwellings as a way to beat the heat. In the 1970s, when George Lucas needed a desert landscape to stand in for the distant home planet of Luke Skywalker, Chott el Djerid was chosen. Some of the film props—seen in this photo—are still standing, and continue to draw tourists into the region.
