The Westminster Opera House was built in the 1850's. The hall, known an Odd Fellow's Hall, was used as a venue for local entertainment. Comedians did routines, plays were performed and minstrels sang. One Saturday night, Marshall Buell, of Alabama, appeared on stage. Buell routine was centered around poking jokes at President Ulysses S. Grant and the union supporters.
Some of the crowd took an immediate dislike to his jokes At one point, stones were thrown at at him. Consequently, he cut his routine short and was headed to his next gig in Hagerstown. The sheriff offered Buell protective custody for the night, he refused.
While saddling his horse in the back of the hall, Buell was attacked. His body was found with his neck cut from ear to ear.
Since the murder , there have been numerous reports of people seeing a ghostly figure making wordless gestures in the back of the building, similar to an actor delivering a monologue.
The building is now home to The Opera House Printing Co.
