Description:
Antietam Farm is located along Mills Road in a rural setting about four miles south of Sharpsburg in Washington County, Maryland. The farmstead consists of a ca. 1844 Federal/Greek Revival brick, two-and-a-half-story, five-bay, double-pile dwelling on an 11-acre parcel on the western side of Mills Road. A non-contributing open five-bay frame equipment shed is located south of the dwelling, and a modern, non-contributing gazebo stands to the west. Contributing farm structures, including a mid-nineteenth-century wagon shed and a brick-and-frame Pennsylvania bank barn, are located on 74 acres on the eastern side of Mills Road. The property is set within rolling hills, pasture, and deciduous trees along the slope of Red Hill, retaining its agricultural viewshed.

Significance:
Antietam Farm illustrates Washington County’s mid-nineteenth-century prominence as a wheat-producing region, with the Showman family among the district’s most prosperous agriculturalists and largest enslavers. Agricultural schedules document the scale of production, while later adaptation to dairy farming reflects continuity of agricultural use beyond the Civil War. The property also played a role in the aftermath of the Battle of Antietam as the headquarters of Union General Ambrose Burnside and the site of President Abraham Lincoln’s October 1862 consultation and review of the Ninth Corps. These events underscore the strategic and morale-building functions of the Union Army in the immediate post-battle period. Additionally, Antietam Farm embodies mid-nineteenth century building traditions through its brick farmhouse, which reflects the transition from Federal to Greek Revival styles, and its Pennsylvania bank barn, notable as the largest in the district and distinguished by rare brick outsheds. Comparative analysis with other Sharpsburg-area farmsteads, including Mount Airy, the Hoffman Farm, the Pry House, and the Sherrick House, highlights Antietam Farm’s unusual three-story porch, substantial full basement, and oversized Pennsylvania bank barn as distinctive features. Together, the agricultural, military, and architectural associations of Antietam Farm make it one of the most intact and historically significant farmsteads in the Antietam Valley.
