Big city life unites the planet. Every habitable continent has metropolitan hot spots that are a hive of activity, a hub of culture - or, to countless millions, the place they call home.

Some thrive on a symphony of car horns while for others there's the rhythmic echo of trains or even ships. The air may hang heavy with spices or fragrant flowers, among buildings that are rarefied or regenerated. There's no universal formula that makes a city illustrious. But the spectacle of a horizon brimming with prominent buildings great and small evokes an anticipatory thrill about what lies at its core. And a skyline is that city's iconic signature writ large on a blank canvas, with no two appearing the same.

A skyline is a window-shoppers guide to what lays in store. It is a visual code that bridges the language gap and shows you at a glance what has made a city great.
