A landmark literally meant a geographic feature used by explorers and others to find their way back to their departure point, or through an area.
In American English it is the main term used to designate places that might be of interest to tourists, due to notable physical features or historical significance.
[citation needed] In urban studies as well as in geography, a landmark is furthermore defined as an external point of reference that helps orientation in a familiar or unfamiliar environment.
In the modern sense, landmarks are usually referred to as monuments or prominent distinctive buildings, used as the symbol of a certain area, city, or nation.
