The Venice Charter is a set of rules that grown-ups made to help take care of really old buildings, like castles and churches, so they don't fall apart.
You know how sometimes you’re playing with your toys and they get dirty and broken? Well, when buildings are really old, they can also get dirty and broken. And it's not just because of toys, but because of things like rain, wind, and even people walking on them.
The Venice Charter helps people who take care of these old buildings know what they can and can't do to make sure the buildings stay the same as they were originally built. This means they can't just knock down walls or replace old stones with new ones. Instead, they have to use special techniques so the building stays the same and keeps its history.
The Venice Charter is important because old buildings are like a time machine. They can help us learn about the past and important people who lived long ago. So, it's really important to take care of them so they're still around for many more years and we can learn from them.
