Biltmore Estate is a really big house that was built a long time ago by a man named George Vanderbilt. It's kind of like a castle, but not really because it's not in Europe. The house has lots of rooms inside, and they are all really fancy and pretty.
George Vanderbilt was a really rich man and he had lots of money. He liked the idea of having a big house where he could live and then share with other people too. So, he decided to build Biltmore Estate in a place called Asheville, North Carolina. It took a really long time to build because it's so big, but finally, it was finished in 1895.
The house has lots of things inside, like a big dining room where you can eat fancy meals with your friends, and a library with lots of books that you can read. There are even secret passageways that you can find if you're clever enough!
Nowadays, people can visit Biltmore Estate and see what it's like inside. They can walk around the gardens outside and see all of the pretty flowers and trees. There's even a winery where you can try different kinds of wine that are made right there.
So, Biltmore Estate is a really big and fancy house that was built a really long time ago. Now, people can visit it and see what it's like inside and outside.
