Fort D

Fort D is a Civil War defensive position featuring earthen walls reinforced with limestone blocks arranged in a geometric pattern. An interpretive building from 1937 occupies the grounds and provides information through displays and signage.

Built in 1861 under the direction of Lieutenant John Wesley Powell, the fort brought together Union soldiers, local militia, and the 20th Illinois Infantry for its construction. It represented one of four defensive works intended to guard the town during wartime operations.

Living history events here showcase soldiers in period uniforms and military practices from the 1860s, giving visitors a direct sense of how troops lived and worked. These demonstrations help explain the daily reality of Civil War service.

The site sits five blocks south of the intersection of Missouri Route 74 and Sprigg Street and welcomes visitors during daylight hours with no admission charge. Self-guided walks around the grounds work well, and informational panels help explain what you are seeing.

Of the four defensive positions built to guard Cape Girardeau, only this one remains visible to visitors today. Local efforts to preserve and maintain the grounds mean you can actually walk on the original earthworks and experience the site as a working military installation from the past.
