The Gen. William Worth Belknap House is a historic building located in Keokuk, Iowa, United States. William Worth Belknap moved to Keokuk from upstate New York in 1853 to practice law. He built this Greek Revival style house the following year. It is a two-story brick structure with a single-story wing. The two story section is original, while the single-story section is an addition, built shortly afterward. The house features narrow window openings with simple stone lintels and sills. It is built on a stone foundation covered with concrete and capped with a low-pitched gable roof whose ridge is parallel to the street. The front porch is not original. Belknap resided here with his mother and two sisters.[2]
