A "landmark" is a recognizable feature or structure that serves as a point of reference in a specific location. Landmarks can be natural, like mountains or rivers, or man-made, such as buildings, monuments, or bridges. They often hold historical, cultural, or architectural significance, making them important for navigation and tourism. Landmarks help people orient themselves in unfamiliar areas and can be used in maps and directions. Famous examples include the Eiffel Tower, the Statue of Liberty, and the Great Wall of China. These sites attract visitors and contribute to the identity of their respective regions.
