Built that year to segregate a black neighborhood from a white subdivision in a federally supported act known as “redlining,” the wall still stands today. In 2006, community activists painted murals on parts of the wall that celebrate African-American culture and commemorate the long, continuing struggle for civil rights.

The wall was meant to keep Sahwarian refugees and fighters from the nationalist Polisario Front out of the country. The Berm is thought to include one of the world’s longest continuous minefields.
