I LOVE NYC!!!
The Vanderbilts bought the entire row of houses behind them and brought in George B. Post and Richard Morris Hunt to build them a palace that would occupy the entire block. When it was completed , the chateau would be the largest home ever built in New York City, with 137 rooms, 37 bedrooms, 16 baths, a library, numerous salons, a baronial dining room, smoking room and a magnificent ballroom.
