Located at the corner of Caroline and Willing Street, the Milton Opera House was designed by architect Walker Willis in the renaissance revival style and built in 1912. It was later renamed the Milton Auditorium and was one of the first brick buildings constructed after a devastating 1909 fire. The walls are four bricks thick and the floors are steel-reinforced concrete. It is the only three-story building in Milton. As many theatres, the second floor balcony surrounds the stage on three sides. The theatre was later named after seven-year-old Imogene Gooch after her parents purchased the building in 1921. The downstairs was once a post office and retail store. The area under the theatre then stood empty for forty years until the Santa Rosa Historical Society acquired it to house the Museum of Local History.
