Okay, so imagine a really old and big building that looks like a castle. That's what Valmer Castle is! It's in a place called Vouvray which is in France. It was built a long, long time ago, in the 16th century. That's like a bajillion years ago in a five-year-old's mind!
Valmer Castle has lots of rooms inside where people used to live a long time ago. It even has a really cool garden that's called a "jardin à la française". That means it's designed to look really pretty and organized with lots of hedges and flowers in special patterns.
People can visit Valmer Castle now and learn about what it was like to live there a long time ago. There are tour guides that will show you around and tell you lots of interesting facts. It's like going on a really fun adventure back in time!
