An object is well known nationally when it is among the most widely recognized places in its country, though not so much worldwide. Its recognition may derive from any noteworthy characteristic, especially for its aesthetics, history, or visibility.
The recognition extends beyond the immediate locality to a national audience. Local recognition has a more limited geographic reach.
Familiarity with a place is distinct from its national landmark protection. The latter concerns a government's legal designation rather than public awareness.
