One of the biggest rooms below ground level is the kitchen. And there are separate rooms for keeping food fresh and cold, and for washing the Vanderbilt's clothes.

Past these rooms we find an indoor swimming pool. This area has several separate small rooms where guests could change into swimming clothes.

SHIRLEY GRIFFITH: We finally come back to the front door of the house. Yet there is still much to see at the Biltmore estate.

To the left of the front door, about fifty meters away, is where the Vanderbilt family kept its horses. It is no longer used for horses, however. It now has several small stores that sell gifts to visitors. Visitors can also enjoy a meal or buy cold drinks and ice cream.

RICH KLEINFELDT: In addition to seeing the main house at Biltmore, you can walk through the gardens. Hundreds of different flowers grow there. A big stone and glass building holds young plants before they are placed in the ground outside.

Past the gardens is the dark, green forest. Trees seem to grow everywhere. The place seems wild. At the same time, there is a feeling of calm order.

There was once a dairy farm on the Biltmore estate. It is gone now. The milk cows were sold. Some of the land was planted with grapes. And the cow barn was turned into a building for making wine.

SHIRLEY GRIFFITH: As we continue to walk, we come to an unusual house in the forest. The road on which we are walking passes through the house. The house was used many years ago by the gatekeeper.
