THe Berm of Western Sahara (also known as the Moroccan Wall or Wall of Shame) is an approximately 2,700 km-long defensive structure, mostly a sand wall (or "berm"), running through Western Sahara and the southeastern portion of Morocco. IT acts as a separation barrier between the Moroccan-controlled areas and the Polisario-controlled section of the territory that lies along its eastern and southern border. THe structure goes by a variety of names, with Moroccan Wall and The Berm being some of those often used. MOroccan authorities prefer the latter. PArties sympathetic to Western Sahara''s independence and the Polisario often use the Polisario''s term, the "Wall of Shame".
