Dubai, United Arab Emirates

Dubai is an extravagant city, which pushes the limits on its architecture and its cultural diversions. The Burj Khalifa, at a height of 828 metres (2,716 feet) and more than 160 stories, is currently the tallest building in the world, though two towers under construction - one in Jeddah and one in Dubai - will top it when they open. The Palm Jumeirah, the first completed of three planned Palm Islands in Dubai, is the world's largest artificial island, and includes high-end housing and hotels. The Dubai World Cup is the richest horse race in the world. Dubai has even built a ski-hill in a mall.

Dubai's economy is based on tourism, banking, and the development of industry-specific zones for different economic activity, such as healthcare services, media, financial services, technology, etc.

I mustn't forget to mention the beaches, the sailing, and the diving!
