Burj Khalifa, Dubai

Officially opened last week, and named by the Ruler of Dubai, after the Ruler of Abu Dhabi - very sensible as he provided the funds to bail out Dubai partially from its horrendous debt problems. This is the world's tallest structure, so I'm guessing it may qualify for entry in Kate's competition. By way of comparison, that is one of the world's larger cranes bottom left!
