These remarkable pictures were captured by photographer Alexander Remnev, a 19-year-old Russian on holiday with friends in Dubai. The images were taken atop some of the city's most famous skyscrapers, including the the Princess Tower - the world's tallest residential building at 1,350ft. Remnev said: "Dubai has amazed me with its skyscrapers and views from them. We love the height of Dubai - it is a city of skyscrapers. We climbed on top of as many as we could.
