Shiloh-Marion Baptist Church and Cemetery, Greek Revival church with cemetery in Buena Vista, United States.

Shiloh-Marion Baptist Church is a one-story wood-frame building with horizontal board siding that rests on stone supports and features a gable roof. The structure follows Greek Revival design principles and sits adjacent to a cemetery with burial grounds.

The building was constructed in 1835 when the area was part of Church Hill, a settlement that once had five churches and an academy. It remains the sole surviving structure from that earlier community.

The church is the last remaining building of Church Hill, a community that once had five churches and an academy. Its National Register nomination links it to the Christian Union faith founded by Reverend George Lynch Smith, whose followers sometimes met in other churches such as this one.

The church stands in a rural setting near Buena Vista, Georgia, and is reached by road, so a car is the practical way to arrive. The building is a single room entered from the exterior; there is no staffed visitor desk, so arrange any interior viewing in advance through the congregation.

The Christian Union faith was founded by the Reverend George Lynch Smith, and its followers sometimes met in other churches, including this one, because the movement did not always own buildings. The 1984 National Register nomination cites this link to a short-lived offshoot of the Church of Christ movement.
