World's Greatest

Mega Cities provide a bustling home to populations of over 10 million. Travel from the high-density living of Shanghai and Bangkok to the sprawling cities of Delhi and Mexico City, each the backdrop for dynamic cultures.

With visionaries, politicians and activists, these metropolises are defined as the official seats of government. Dublin, Washington and Taipei share broad avenues, museums and monuments, but are as varied as the countries they represent.

Some of the most stunning cities are port cities--Sydney, Rio, Cape Town--and are also some of the most culturally diverse and vibrant. The great maritime cities of the world bridge countries and continents and unite the global community.

In Ancient Cities we journey to these ancestors of influence such as Luang Parabang, Vienna and Istanbul where religious and cultural centers have shaped the ways in which we view the world around us and continue to do so in modern times.

Brave the frontiers of the world’s most remote cities. More than distant trading posts and isolated regional hubs, cities like Alice Springs, Jaipur and even Las Vegas serve as gateways to the wild places of the Earth.
