This octagonal house, built by Haller and Julia Nutt, is the biggest in US and is said to be one of the grandest in the world. The house is an incomplete one with the war between states interrupting its construction. The artwork in the basement rooms is outstanding work of art whereas the upstairs provides a glimpse of intricate details. It is a wonderful scene considering the surroundings and the marvelous architecture of the house. The upper part with the dome and the upper point figure is quite a standout feature.
