Recently, photographer Amos Chapple spent some time in Saint Petersburg, Russia's second-largest city. He used a small drone to lift his camera high above the cathedrals and fortresses, capturing some amazing aerial photos. Chapple: "There's a legend in Russia that Saint Petersburg was constructed in the blue heavens and lowered in one piece into the marshland, 'for how otherwise could a city so beautiful exist in a region so bleak.'" Chapple, has previously showed us Stalin's Rope Roads, and took us on a trip to Turkmenistan. [12 photos]
