- Du Bois School Addition (demolished) - Summit OKThis school near Muskogee was originally constructed in 1925. It was listed on the National Register in 1984 as "the only extant educational facility associated with Summit, an all-black town founded in 1896. Further, it was one of the few remaining schools in Oklahoma constructed as an all-black school during the era of segregation which retained its historic integrity." (nr_shpo.okstate.edu) The WPA built an addition to the school in the late 1930s, which was "approximately 35' x 85' and finished with red brick laid in the running bond." (NRHP form) The building burned down in 1991.
