Thespian Hall was constructed between 1855 and 1857 and opened on July 3 of that year at 522 Main Street in Boonville, Cooper County. The two-story rectangular brick building follows a Greek Revival design — a formal, spare style chosen deliberately to communicate cultural legitimacy in a town that had been founded barely four decades earlier.
The hall's claim as the oldest continuously operating theater west of the Alleghenies is supported by the historical record: it has remained in active theatrical use, with gaps only during wartime conversion, since its opening. The Civil War reached Boonville directly — the Battle of Boonville, one of the war's earliest engagements, was fought nearby on June 17, 1861. Union forces subsequently occupied and converted Thespian Hall into barracks, a hospital, and, for a period, a morgue for soldiers who died of wounds or disease during occupation.
The Friends of Historic Boonville acquired the hall in 1975 as a gift from the Kemper Foundation of Kansas City and undertook a substantial restoration. The theater has been listed on the National Register of Historic Places since 1969. It remains the home of the Boonville Community Theater and hosts the Missouri River Festival of the Arts annually. Group tours are available by appointment through the Friends organization.

The most consistent paranormal account at Thespian Hall concerns a figure staff and investigators have taken to calling 'Mrs. X' — a woman in period dress with gray hair who appears seated in the audience area during rehearsals and after-hours access. A photograph purportedly capturing her image circulates among local paranormal investigators, though the source and chain of custody for the image are not independently verified in available sources.
A November 2020 paranormal investigation documented by KC Ghosts produced additional accounts: ragtime music audible in the building when no recording equipment or instruments were present, and wig stands from the theater's costume department found repositioned from where staff had left them. Both are the kind of detail that resists simple mechanical explanation in a building with documented security access.
The Civil War conversion of the hall into a hospital and morgue gives the paranormal accounts a historical grounding. The building held the injured and the dead during Union occupation of Boonville, and some of those men died on the premises. Whether 'Mrs. X' connects to that period or to Thespian Hall's theatrical history is an open question the available sources do not resolve.

The Fabulous Fox Theatre opened in January 1929 as one of five 'Fox' picture palaces commissioned by film magnate William Fox. Designed by C. Howard Crane in a 'Siamese Byzantine' style, the 4,500-seat auditorium was the second-largest in the United States at its opening. After decades of decline the theatre closed in 1978 and was restored by the Fox Associates beginning in 1981, reopening in 1982 as the centerpiece of Grand Center.

The building opened on October 8, 1916 as the Electric Theatre on a block that had been almost entirely destroyed by a major fire in 1913. It operated as the Fox Theatre from 1928 until 1982 and now houses the History Museum on the Square.

The Shepherd of the Hills property served as a Confederate Army sentry post during the Civil War at Inspiration Point. Harold Bell Wright used the Ozark homestead as the setting for his 1907 novel, and the outdoor drama based on that novel has run continuously since 1960.
