The National Register of Historic Places has listed the Lithonia Historic District in DeKalb County in its registry. Lithonia’s nomination was sponsored by the city itself and the Arabia Mountain National Heritage Area Alliance Inc.

Originally a crossroads settlement that served the trading needs of a small community of rural farmers, the city grew with the development of the Georgia Railroad, now CSX Rail Inc. The rail line, which runs through the commercial center of town, connected Lithonia with Atlanta and Augusta in 1845.

The district includes a large number of community landmark buildings, including the Masonic Lodge built in 1916; the Lithonia First United Methodist Church, originally named Lithonia M.E. Church in 1910; Antioch Baptist Church in 1911 and “The Seminary” which was built in 1895 and individually listed in the National Register in 1978.
