Located outside Erfoud, Morocco, along the N12 road connecting Merzouga to Alnif, the Gara Medouar is a sedimentary rock formation which by the erosion processes had taken on the appearance of a crater.
Nicknamed the Portuguese Prison due to his use as a sheltered area for the slave trade from Africa to Portugal, the rock formation was also used as a Moroccan military base.
Fascinating movie landscape, Gara Medouar has appeared in many films: Spectre (2015), Prince of Persia: The Sands of Time (2010), The Mummy (1999), The Mummy Returns (2000) and the TV series The Secret of the Sahara (1998).
