John McGreer Barn and Crib

John McGreer Barn and Crib are historic structures located in rural Harrison Township, Lee County, Iowa, United States. They are located on a farm northwest of the town of Donnellson. The agricultural buildings were listed on the National Register of Historic Places in 2001. The barn was built in 1884 in the Pennsylvania barn style. It measures 76 by 48 feet (23 by 15 m), and features a cupola on top. The corn crib is located west of the barn. The 32-by-26-foot (9.8 by 7.9 m) structure was built around the same time as the barn. It has a round arch window in its gable front. The barn and corn crib were two of 13 extant buildings at the time of their nomination on the former John and Julia McGreer farmstead.
