In orientation and mobility, a landmark is a stable, recognizable feature in the environment that you can detect with your senses and that stays in place over time. Because it is permanent, you can rely on it to tell you where you are or to guide your route on different trips. Landmarks can be perceived in multiple ways—visual features like a distinctive building, a fountain you can hear, a textured surface you can feel with your hand or foot, or even a persistent scent—so long as the feature remains noticeable and stable. For example, passing by a tall clock tower, a unique sculpture, or a persistent sound from a fountain provides a reliable reference point you can use to orient yourself.

Other terms reference different ideas. Information points or cues refer to specific pieces of information you might use along a route, which aren’t necessarily permanent features of the environment. Cartographic information is map-based data rather than something you physically sense in the environment. A secondary landmark is still a landmark, but it’s typically less prominent or reliable than a primary, highly noticeable landmark. The essential idea is that a landmark is a lasting, detectable feature that supports orientation and navigation.
