The Birwood Wall is significant for its association with the federal policy of redlining that ensured neighborhoods would remain racially segregated the mid-twentieth century. The wall is a six-foot-high solid concrete wall that stretches for three blocks. It was constructed in 1941 to physically divide two growing neighborhoods, one White and one Black. It is a rare surviving, tangible, human-scale example of the lengths to which the government, the real estate profession, private developers, and White residents were willing to go to keep neighborhood populations the same race.
