Anna C. Diller Opera House

The Anna C. Diller Opera House is a historic three-story building in Diller, Nebraska. It was built as a two-part commercial block in 1912 thanks to a donation by Anne C. Diller, whose late husband William H. Oilier had co-founded Diller. Inside, there is a 42 feet wide by 67 feet long auditorium with a 20 feet wide by 14 feet high proscenium arch. The building has been listed on the National Register of Historic Places since July 6, 1988.
