Silesian walls are like big buildings made of stones that were built a long time ago in a place called Silesia. These walls were used to protect people and their villages from enemies and bad things that might happen.
Imagine you are playing with blocks and you build a really big structure to protect your toys from other kids or from something that might knock them down, like a ball or a clumsy pet. Silesian walls were like that, but even bigger and stronger.
People in Silesia built these walls with big rocks called boulders, which were found in nearby areas. They used special tools to make the rocks fit perfectly together like a puzzle. Sometimes, they would even put mud or clay in between the rocks to make them stick together better.
Nowadays, some of the Silesian walls are still standing and are considered important historical landmarks. People come from all over the world to see them and learn about the history of Silesia.
