Built in 1895, or rather completed then, was the "pleasure house" of George Vanderbuilt. The house sits on 8000 acres and it run by a decsendant. The house was opened to the public in 1930 due to a way to increase tourism during the Depression. The cost of admission for a self guided tour of the house and gardens also allows a visit to the winery and the farms. We didn't have time to go to those places but went through the house and most of the gardens. It is probably the most spectacular house I have ever been to. Walking through, I can imagine being a guest staying in one of the 33 guest rooms. There are 44 rooms on the tour and things are laid out very well to allow people to go through efficiently. If you are in the area I strongly recommend you visit.
