It was common practice in many African-American communities in early 20th century Georgia for churches to construct schools. This was due to the fact that the state was notoriously negligent in the construction and upkeep of schools for black students. The Rosenwald Foundation and the American Missionary Association were two outside concerns that contributed to the cause of African-American education, but I haven’t been able to link either group to Walker Grove and therefore believe that it was built by the members of Walker Grove Baptist Church. It’s located on the same property. I believe this was built in the 1910s or 1920s.
