Eugene S. Thrall, a man who had been co-owner of the building since 1867, bought out the rest of it in 1888 and remolded the front, adding the opera house styled facade you see today. He also changed the name of the building to Thrall's Opera House. It was used as an opera house until 1910, after which it was used the next few decades as a nickelodeon movie house and a Conoco gas station. In 1964 the Indiana Department of Natural Resources bought the building, thanks to the efforts of the Harmonie Associates, renovated it to be used as a theater once again. Thrall's Opera House still hosts various musical productions on its stage, as well as workshops, lectures, and balls. Visitors can go to the opera house and marvel at the style of its auditorium room, which harkens back to late 19th-century America.
