A "landmark" is a notable feature or structure that stands out in a landscape, often serving as a point of reference. Landmarks can be natural, like mountains or rivers, or man-made, such as buildings or monuments. They help people navigate and can also hold historical or cultural significance, making them important to local communities and visitors alike. Famous landmarks, like the Eiffel Tower in Paris or the Great Wall of China, attract millions of tourists each year. These sites often symbolize the identity of a place and can tell stories about its history, architecture, and the people who live there.
