Siloam Baptist Church, Baptist church in Marion, Alabama.

Siloam Baptist Church is a brick building in Marion featuring Greek Revival design with a symmetrical front, large columns, and rectangular windows arranged in three vertical sections. Modern systems including air conditioning, an elevator added in 2007, and classrooms for religious education are part of the interior layout.

The church was founded in 1822 and became the center of a religious movement that shaped the Southern Baptist Convention through the Alabama Resolutions of 1844. These resolutions had lasting effects on how Protestant communities organized themselves across the nation.

The Memorial Parlor holds the table around which the Southern Baptist Convention's Home Mission Board met in 1845, when the church hosted the organizational meeting. The name Siloam refers to the pool of Jerusalem in the Gospel of John. The congregation dates to June 1822, founded with the town of Marion by the preacher Charles Crow.

Siloam Baptist Church is an active Southern Baptist congregation, not a site open for tours; visits depend on attending a service or contacting the church in advance. The 1848 brick building stands on a spread footing rather than a concrete foundation, and its steeple was planned to rise 120 feet from the base. The Memorial Parlor keeps the table used at the 1845 organizational meeting of the Southern Baptist Home Mission Board.

The building helped establish two educational institutions: Judson College in 1838 and Howard College, which later became Samford University, in 1841. This connection to higher education reveals an unexpected role beyond typical church functions.
