Known as Krung Thep in Thai (which means "City of Angels"), Bangkok is the business and political center of Thailand. The population of about 12 million people is soaring in the capital city. Traffic and pollution are soaring, too. Bangkok features some of Thailand's most breathtaking architectural structures, including the Grand Palace. It is also home to a modern Skytrain and subway system. A hot spot is Ratchada Road, which is often compared to New York City's Times Square. (GETTY IMAGES)
