A round barn was an exciting new idea for Scott County farmer Charles Nebergall. He discovered an architect named Benton Steele, who had built dozens of round barns in Indiana and Kansas, and hired him to design and construct this barn in 1914. It is 56 feet in diameter and features clay tile with square windows on the bottom half, board-and-batten siding with rectangular windows on the upper half, and a two-pitched conical roof with a cupola. It has no silo.
Originally a central drive divided the interior between the horse stalls and cattle stanchions, with grain bins and feed areas for the animals on each side of the central drive, as well as separate hay chutes. It was owned by the Nebergall family until 1992, is now owned by the John Penne family, and is filled with antiques on two levels. The location is 9478 145th St., Davenport.
