Okay kiddo, do you know what a "landmark" is? It's something that helps you know where you are or something special that you can look at and remember.
Let's say you and your family are driving to the beach. Along the way, you might see big things like buildings or statues that are famous and help you know where you are on the map. These things are called landmarks.
For example, the Eiffel Tower is a famous landmark in Paris. People see it and they know they are in Paris. The Statue of Liberty in New York is also a landmark. It's big and has a special shape that people remember.
Landmarks can be natural too. Like a mountain or a river. They help people remember where they are and can also be used for directions.
So, remember kiddo, a landmark is something special that you can look at and remember. It helps you know where you are or where you need to go.
