Sardis is on Farm Road 2705 five miles west of Mexia in north central Limestone County. It was established, probably in the 1870s, by a former slave and Primitive Baptist preacher. The Sardis school had thirty-seven students and one teacher in 1897. A church and a few scattered houses marked the community on county highway maps in the 1940s, but only the church was shown on maps in the 1980s.
