Est. 1847 · One of Only Two Surviving Octagonal Homes in Kentucky · Civil War Field Hospital · Confederate Soldiers Buried On-Site · Kentucky Confederate Studies Archive
Andrew Jackson Caldwell began construction of his unusual home in 1847, inspired by the architectural movement sparked by Orson Squire Fowler's 1848 treatise on octagonal design. The project took approximately 12 years to complete, finishing around 1859-1860 as the country moved toward civil war. The two-story red brick structure, featuring Flemish bond brickwork on the primary facades, remains one of only two surviving octagonal buildings in Kentucky.
Caldwell chose his home's design as a deliberate statement of distinctiveness, and the property's 300 acres in Simpson County placed it in strategically significant terrain near the Kentucky-Tennessee border. When war came, Octagon Hall became a site of convergence for both armies. Caldwell was a committed Confederate sympathizer; he sheltered retreating Confederate soldiers and hid them in spaces built into the structure — concealed areas under the front steps, above closets, and behind kitchen cupboards that investigators have since documented.
As many as 10,000 Confederate soldiers camped on the property's grounds before retreating south into Tennessee. The building served as a field hospital for Confederate wounded. Union forces, aware of Caldwell's sympathies, poisoned the property's well in retribution. One of John Hunt Morgan's Raiders died at Octagon Hall and is buried near the Caldwell family plot; a separate burial area exists for the enslaved persons who worked the property.
Caldwell died in 1866. His wife Harriet remained in the home until after her death. The property passed through several owners before the Octagon Hall Foundation acquired it in 2001. Director Billy D. Byrd developed the facility as a nonprofit museum emphasizing both its Civil War history and its investigation potential. The venue has been featured on Ghost Adventures and Kindred Spirits and runs a regular schedule of public and private paranormal investigations.
Sources
The paranormal case at Octagon Hall is inseparable from its documented history. The two cemeteries — one for the Caldwell family and Confederate dead, one for enslaved persons buried in a separate plot — are both accessible during investigations and both generate independent reports from unrelated investigation teams.
Mary Elizabeth Caldwell is the most specifically identified entity. The daughter of Andrew Caldwell and his first wife Elizabeth is said to have died in the early 1850s after her dress caught fire in the basement kitchen — the traditional account places the incident in 1851, though some researchers note that census records complicate the timeline and the exact year is disputed. Her presence is associated with the basement areas of the main house and reported as a child figure, smaller than an adult, in photographs and by investigators working with visual equipment.
Confederate soldiers are the most frequently reported category of apparition on the grounds. The property's history of hosting thousands of soldiers, combined with the battlefield hospital function and the known burials, provides a documented biographical pool for reports of uniformed figures moving through the outbuildings and the far corners of the property after dark.
The investigation conduct rules at Octagon Hall are notable precisely for their specificity. The museum explicitly prohibits Ouija boards, seances, human pendulums, dark magic, and rituals — a policy that distinguishes it from venues that impose no investigative limits. The rationale, per the museum's documentation, is protection of the site and its resident presences. Whether one assigns meaning to that rationale, the practical effect is an investigation environment with explicit ethical constraints that some investigators find more respectful of the historical context.

Franklin, KY
Octagon Hall is an 1847 octagonal antebellum house in Franklin, Kentucky, listed on the National Register of Historic Places in 1980. It is one of two surviving octagonal structures in Kentucky and operated during the Civil War as a hospital for soldiers of both sides and a hideout for Confederate troops. Today it functions as a museum.
Marietta, GA
The Kennesaw House was built in 1845 as a cotton warehouse on what is now Marietta Square, adjacent to the railroad tracks that would define its Civil War history. Purchased by Dix Fletcher in 1855 and converted into the Fletcher House hotel, it served as both a staging point for the famous Great Locomotive Chase of April 1862 and as a hospital and morgue for Confederate and Union forces during Sherman's Atlanta campaign. Today it houses the Marietta History Center.
