Okay kiddo, so there's a place called the Skull Chapel in Czermna in Poland. It's a special chapel where there are lots of human skulls and bones.
A long, long time ago, some folks in that area were in a big war and many people died. Instead of burying all of the bodies, some folks decided to collect their bones and make a chapel out of them.
Inside the chapel, there are bones arranged in different ways. Some are arranged into shapes like a cross or a heart. Others are piled up on top of each other to make big stacks. You might see bones from different parts of the body, like the legs, arms, or even the rib cage.
It's a little bit spooky to visit the Skull Chapel, but many people go there to remember their loved ones who have passed away. They believe it's a special place to honor and remember those who have gone before us.
