Pennsboro is an unincorporated community in southern Dade County, in the U.S. state of Missouri.
[2] Pennsboro was founded in the 1880s, and named after William Penn, a Dade County pioneer.
[5] Just prior to the abandonment, the depot was loaded in one piece onto a flat car at Pennsboro and transported down the line to Mt.
Vernon, where it was replaced that community's depot that had recently been destroyed by fire.
However, the one-room rural schools themselves were not consolidated until the mid-1930s; the state board of education excoriated the Pennsboro C-3 district in its 1932 annual report for maintaining what they termed the four inefficient one-room schools rather than consolidating students at a central point and allowing teachers to teach fewer grades.
