Organized about 1879 as Lytle Gap Methodist Episcopal Church, South, this fellowship first met in private homes and a schoolhouse. The church name changed after the community became known as Potosi in the 1890s. This sanctuary, the second for the church, was constructed in 1906 during the pastorate of the Rev. E.L. Sisk. Built on a foundation of stones from a local creek, it features Victorian gingerbread detailing.
