Okay, so have you ever been to a haunted house or seen skeletons on Halloween? Well, in a town called Czermna in Poland, there is a special chapel where there are lots and lots of real human bones and skulls!
A long time ago, there was a really big war and lots of people died. Their bodies were buried in a big graveyard, but eventually, the graves got too crowded and there wasn't enough space. So, some of the bones were taken out and brought to the Skull Chapel.
The Skull Chapel is a little building with walls and a roof, just like a tiny house. But inside, there are lots of bones that have been put together into shapes. For example, there are piles of skulls that make a square shape, and there is even a big chandelier made out of skull bones hanging from the ceiling!
It might sound a bit scary, but many people think it's actually quite beautiful and interesting. The people who built the chapel wanted to show that death is a natural part of life and that we should respect and honor those who have passed away.
So, if you ever visit Czermna, you might want to go and see the Skull Chapel and learn more about the history and meaning behind all the bones. But just remember, it's not a place for playing or being silly, it's a place for being respectful.
