St. Thomas Protestant Episcopal Church, constructed in 1892–1893 near Eastover in Lower Richland County, is a well-preserved example of a small rural church displaying elements of the Gothic Revival style. The simple one-story frame building is sheathed in weatherboard and rests on a brick-pier foundation beneath a steep longitudinal gable roof. Its front elevation features a small gabled porch sheltering a Gothic-arched entrance, while lancet windows and other pointed-arch openings provide restrained Gothic detailing. Inside, the church retains beaded-board wainscoting and a ceiling supported by exposed beams and trusses, illustrating the straightforward craftsmanship of late-nineteenth-century rural ecclesiastical architecture.

The church grew from an Episcopal mission established in Lower Richland County during the 1870s to serve the area’s African American population. Reverend Thomas Boston Clarkson oversaw an earlier chapel known as Saul Chapel, built with funds donated by Reverend James Saul of Philadelphia; after that building burned in 1891, construction of the present St. Thomas Church began in 1892, reportedly with assistance from members of the congregation. The church represents the establishment and continued development of African American Episcopal institutions during the Reconstruction and post-Reconstruction eras and remains an important landmark in the religious and community history of Lower Richland County.
