Cave castle

A cave castle is like a house built into a big hill or mountain. Imagine if you were playing with your toys and you made a fort using blankets and pillows, but instead of using blankets and pillows, it's a big hill or mountain that protects you.

People would make the cave castle their home by digging tunnels and rooms into the hill or mountain. Some cave castles were made a really long time ago by people who wanted to hide from bad guys who might want to hurt them.

Cave castles have a special kind of door that is really heavy and can only be opened from the inside. This helps keep the people inside safe from any danger outside. They would also have things like a well or a water source inside the cave so they would have water to drink.

Overall, a cave castle is like a secret hideout that people live inside and protect themselves from danger.
