A landmark is a significant and easily recognizable feature or location that serves as an identifying point for navigation, orientation, or historical reference. It can be a natural formation such as a mountain or river, or it can be a man-made structure like a building, monument, or statue. Landmarks often have cultural, social, or economic importance and are used to define boundaries, establish locations, or provide direction. They serve as points of interest for tourists and travelers, and they play an important role in shaping the identity and history of a place.
