14. Dubai, United Arab, Emirates

Is this a mirage in the Middle East ? Seemingly out of nowhere emerges a city in the middle of a desert. This is Dubai , a city that produces only the best modern architecture in the world. Already home of the world's tallest all-hotel building and the tallest all-residential building in the world, AND currently proposed to build the world's tallest building, this skyline might just leap to the number 1 spot in the near future. While the skyline is not so dense, each building is a marvel all on its own. As a skyline it probably can't compete with the larger cities, however the individual buildings in this city are by far the greatest examples of modern architectural accomplishments. All seven structures in this city at over 200 meters tall were built in 1999 or later - that's how new this city is.

Metro/Urban Population: 1.6 million
