Mann School No. 2, also known as Sioux Township #2, is a historic building located west of Moorhead, Iowa, United States. Built in 1884, the building is a simple rectangular frame structure with a gable roof. Originally three bays long, an addition in the 1920s that added a cloak room and internal stairway to the basement, extended it one more bay. Located in the Loess Hills, this school differed from one-room schoolhouses on the prairie, in that it was located near the center of a cluster of families rather than at the center of four sections.^[2] Parents of the students who were educated here took responsibility for the upkeep and maintenance of the building and grounds. The building remained in use as a school until 1945 when the teacher expectantly left. Enrollment had been low to begin with so the district sent the students to a neighboring rural school and then to Moorhead. The building continued as a polling place after the school was formally closed in 1945. It was listed on the National Register of Historic Places in 2001.^[1]
