Okay, imagine you go to a fancy museum and you see a special symbol that looks like a lion with wings. This symbol is called the Lion of Saint Mark.
A long, long time ago, people in a place called Venice wanted to have a special symbol to represent their city. They chose a lion because they thought they were very strong and brave. But they didn't want just any lion, they wanted a special one. They wanted a lion with wings!
So they made a drawing of a lion with wings and put it on all kinds of things. They put it on flags, on doors, on buildings, on boats, on everything that belonged to their city.
Now people all over the world know about the Lion of Saint Mark and they recognize it as a symbol of Venice. It's like a special sign or badge that shows you belong to that city.
So if you ever go to Venice, keep an eye out for the Lion of Saint Mark!
