Old Westbury Mansion and Gardens
Upstate New York has a plethora of incredible historic mansions. Old Westbury Mansion and Gardens http://oldwestburygardens.org/ provides so much history about fine antique furniture, beautiful art and the history of the gilded age. If you are ever traveling to Old Westbury, NY, the house and surrounding neighborhoods are fabulous, and definitely worth a visit. Photos are not allowed inside, but I was able to get one picture of the foyer.
