Connelly-Harrington House, Siloam Springs

At the corner of East University Street in Siloam Springs stands an early twentieth-century Prairie-Craftsman house that belonged to one of the most consequential businessmen in early-twentieth-century northwest Arkansas.

Connelly Harrington moved from Missouri to Siloam Springs and built the Benton County Hardware Company into a three-location mercantile operation. He then founded the Farmers National Bank, channeling capital into commercial development across the region. The house he built, a two-story American Four-Square with wide overhanging eaves and impressive square porch supports, reflects the Prairie School influence that was filtering west from Chicago at the time.

John Brown University bought it after Harrington and his wife died in nineteen thirty-five and used it as a hospital until nineteen forty-eight. It was added to the National Register of Historic Places in nineteen eighty-eight.
