The fortifications lie in uninhabited or very sparsely inhabited territory. They consist of sand and stone walls or berms about in height, with bunkers, fences, and landmines throughout. The barrier minebelt that runs along the structure is thought to be the longest continuous minefield in the world. Military bases, artillery posts and airfields dot the Moroccan-controlled side of the wall at regular intervals, and radar masts and other electronic surveillance equipment scan the areas in front of it.
