Sky lines

A skyline is the horizon created by a city's overall structure, or by human intervention in a non-urban setting or in nature.

City skylines serve as a kind of fingerprint as no two skylines are alike. For this reason, news and sports programs, television shows, and movies often display the skyline of a city to set a location.

Paul D. Spreiregen, FAIA, has called a skyline "a physical representation [of a city's] facts of life ... a potential work of art ... its collective vista."
