Transparencies and Negatives Collection: Historic photographs. Thrall�s Opera House: This is the remodeled original Rappite Dormitory House No. 4. It went through many changes during two hundred years of continuous use. In 1857 the building became the Union Hall, the first presentation being �Damon and Pythias� and in 1879 Will Crisp painted a new stage curtain for the theater. The doors opened at 6:30 pm and the curtain rose at 7:00 pm. By 1893 the theater had been remodeled and had become Thrall�s Opera House but by 1907 it was known as Pratt�s Opera House before being converted into a garage in 1913. The last event which was held in the old building was the 1913 New Harmony School Commencement ceremony. The building remained a garage, with one gasoline pump, until sometime before 1943, after which it was used as a fire house by the town.
