Originally constructed for the Baptist congregation in DuBois, this building first held services in December 1894. In 1895, Sidney Fuller converted it into an opera house with excellent acoustics and seating for 800, half of it in opera chairs. Its top gallery, known as "peanut heaven," often seated children who received free passes for helping set up shows. A 30'-50' stage was lit by electric footlights and additional illumination from the wings, and the facility included five dressing rooms for traveling companies and its own six-piece orchestra. Managed by A. P. Way, who later built the Avenue Theater, it welcomed traveling theater troupes and musicians arriving at the B. R. & P. Railroad Station and parading up West Long Avenue. Companies often stayed for two or three days to perform plays and musicals, including works of abolitionist Stephen Foster, and John Philip Sousa and his marching band performed here. In 1906, the building returned to its original use as the First Baptist Church. It was sold in 1972 to the congregation of Bethany Covenant Church, which moved from Quarry Avenue; that congregation had begun in 1898 as the Swedish Congregational Mission Church, with services conducted in Swedish until 1927.
