On a recent trip to Dubai, rooftopper and photographer Alexander Remnev took this dizzying self-portrait from the top of the Princess Tower, the tallest residential building in the world. The Princess Tower is 101-storeys and stands 414 meters (1,358 ft) tall.

The nineteen-year-old photographer, who was on holiday with friends, explored as many rooftops as he could. You can see the complete photo series on his LiveJournal blog.
