The Back of Dent House
The Dent House was owned by Ulysses S. Grant's in-laws, and eventually passed to him and his wife, Julia Dent Grant.
The color is close to original. It was intentionally ostentatious - - the forerunner of the bright colors of Victorian homes.
If you enlarge (press L) you'll notice that the various parts of the home are not square, and do not fit well with one another.
