Okay kiddo, have you ever been to a really big and beautiful church called a cathedral? Well, there's one in a place called Gloucester in England. There's a man called Christopher Whall who worked there a long time ago.
Now, Christopher Whall was very talented at making really beautiful things called stained glass windows. These are big windows that have different colors and pictures on them, like a really pretty picture book. And guess what? Christopher Whall was really good at making these windows.
So, when the people at Gloucester Cathedral needed someone to make some new stained glass windows for their church, they asked Christopher Whall to help. He made lots of beautiful windows with different pictures on them, like angels and saints.
Even though Christopher Whall isn't there anymore, people can still see his beautiful stained glass windows at Gloucester Cathedral today. It's like he's left a really special piece of art for everyone to enjoy!
