well known locally
An object among the most widely recognized places in its immediate vicinity, with less national or worldwide recognition.
An object is well known locally when it is among the most widely recognized places in its immediate vicinity (e.g. city, county, or state), though not so much nationwide or worldwide. Its recognition may derive from any noteworthy characteristic, especially for its aesthetics, history, or visibility.
The relevant audience is the surrounding area, which can be a city, county, or state. The distinction concerns the geographic reach of familiarity rather than a specific reason for fame.
Local landmark protection is a separate legal designation. A place can be familiar to local people without having that protection.
