The Pentagon Barracks stand at the corner of State Capitol Drive and River Road in Baton Rouge, built between 1819 and 1825 under the direction of U.S. Army Captain James Gadsden on the site of the demolished Spanish Fort San Carlos. Gadsden designed four two-story brick structures — later five — arranged around a pentagonal courtyard, intended to garrison troops along the lower Mississippi. The complex was added to the National Register of Historic Places on July 26, 1973.
During the antebellum period the barracks saw continuous military occupation, and the site changed hands dramatically during the Civil War. Confederate forces held Baton Rouge in the early months of the war before Union troops captured the city in May 1862 following the fall of New Orleans. The Battle of Baton Rouge on August 5, 1862, briefly threatened Union control, and the barracks served as a staging and hospital point for federal troops.
Between 1860 and 1869 the complex housed Louisiana State Seminary of Learning and Military Academy — the predecessor of LSU — before the university relocated. In later decades the buildings were converted to state government use. Since the mid-twentieth century the Pentagon Barracks have provided residential apartments for Louisiana state legislators during legislative sessions, a use that continues today.
Maintenance staff and longtime residents have reported encountering a figure they describe as a dark, featureless mass — commonly called the Shadow Man — in the interior corridors and stairwells. Separately, witnesses describe the silhouettes of uniformed men pacing the second-story balconies at night, figures consistent with mid-nineteenth-century military dress.
Sources
The most frequently reported figure at the Pentagon Barracks is not a soldier but a shapeless dark mass that witnesses describe as distinctly hostile in character. Maintenance workers conducting after-hours repairs have encountered it in stairwells and lower corridors; some have refused to return to certain areas alone. The figure has been reported independently by multiple building staff over the years.
Separately, residents and visitors have described seeing the outlines of uniformed men on the second-story balconies facing the courtyard, particularly in the evening hours. The figures move with deliberate, measured pacing before disappearing. Given that both Confederate and Union troops occupied the complex during the Civil War, witnesses often decline to assign them to a particular side.
No formal paranormal investigations have been published for the Pentagon Barracks as a primary subject. The haunting accounts circulate primarily through local oral tradition and tourism documentation collected by Visit Baton Rouge.
Notable Entities
Walk the perimeter of the Pentagon Barracks complex on the State Capitol grounds, view the five brick buildings dating to 1819–1825, and read historical markers. The balconies where phantom soldiers have been reported are visible from the exterior courtyard.

Baton Rouge, LA
Constructed between 1836 and 1838 by the U.S. Army, the powder magazine is one of only two surviving buildings from the Baton Rouge Arsenal and Ordnance Depot. It held up to 3,000 barrels of gunpowder and withstood artillery fire during the August 5, 1862 Battle of Baton Rouge. Listed on the National Register of Historic Places in 1973, the restored structure now serves as a museum operated by the Louisiana Secretary of State.
Dillon, MT
Bannack State Park preserves Montana's first territorial capital and one of the West's most intact ghost towns. Founded after the July 28, 1862 gold strike at Grasshopper Creek, Bannack grew to a peak population of approximately 10,000 before declining through the late 19th and 20th centuries. More than 50 historic structures survive along the original main street.
Key West, FL
Fort Zachary Taylor in Key West, Florida began construction in 1845 as part of a post-War of 1812 coastal defense network. Yellow fever epidemics repeatedly slowed construction through the 1850s, killing significant numbers of the garrison. Designated a National Historic Landmark in 1973, the fort now holds the largest documented cache of Civil War armaments in the United States.
