Rosecliff was the third mansion on our list, and the only of the bunch that can still be used for functions.
This one features a massive ballroom and is far less of a house as much as a support structure for that single ballroom. In fact that main attraction has been featured in a number of movies for its abundant grandeur.
The coolest part of the building in my eyes was the painting of the coffered ballroom ceiling. It was painted to imitate a Roman or Grecian courtyard. The center painting panel was a blue sky, and all around the edges of the room smaller paintings showed flower filled sconces at a perspective that would hint at them decorating the pillars of an ancient Athenian courtyard. It was a cool effect.
Unfortunately, outside of a staircase that would make a king feel at home, the rest of the home was pretty blah. Think Motel 6, except from the gilded age.
