Raphael Olivier's photographs of North Korea reveal Pyongyang's unique architecture

North Korea is no longer the tourism black spot it once was, French photographer Raphael Olivier has travelled to the notoriously secretive nation's capital to capture its particular architectural style.Left fascinated by Pyongyang after a one-day trip from China, Olivier returned to the city last month to spend more time documenting its buildings and monuments. Their style is based on austere Soviet architecture, as the USSR helped rebuilding work after the Korean War. However, years of being cut off from much of the rest of world has led to a unique style that blends Stalinist scale with quirks taken from Korean culture.
