Our Lady of the Underpass



Our Lady of the Underpass was a salt stain and purported appearance of the Virgin Mary under the Kennedy Expressway along Fullerton Avenue in Chicago  that was noticed in 2005. The site became a pilgrimage site for local Catholics as well as a general curiosity. Later, it became a target for various acts of vandalism. The Illinois Department of Transportation determined that the stain was likely formed by salt run-off.

Cultural influence
