The National Park Service notes that Lithonia, meaning "city of stone" in Greek, grew into a busy quarry town, and that Lithonia granite was shipped out for buildings such as the U.S. Naval Academy in Annapolis. Historic downtown Lithonia is listed as one of the sites of the Arabia Mountain National Heritage Area.

The heritage area's Davidson-Arabia Mountain Nature Preserve is a DeKalb County preserve of about 2,550 acres around Arabia Mountain, one of the area's granite outcrops. DeKalb County's master plan for the preserve says the Davidson Granite Company donated the original land in 1972. The preserve's nature center is in neighboring Stonecrest.

The City of Lithonia covers only about 0.9 square miles, and many homes with a Lithonia mailing address are outside the city limits, in Stonecrest or unincorporated DeKalb County. Check the property's tax record so you know which city, if any, a home is in before you compare taxes and services.
