Every day, Paris’ six railway stations welcome over 3,000 trains and more than a million travelers coming from France and all over Europe. The stations’ sizes are impressive: Gare du Nord is bigger than the Louvre or Notre-Dame de Paris. These railway stations are architectural landmarks and a model of urban planning despite the radical changes they’ve undergone since their construction in the middle of the 19th century. How did the railway stations manage to absorb the boom of travelers in just a few decades? What colossal works were necessary to erect and then modify these now essential buildings? From the monumental glass walls of Gare du Nord to the iconic tower of Gare de Lyon, to the first-ever all-electric train station, each has its own story, technical characteristics, and well-defined urban image.

Gombessa Expedition 3 Protected by an international treaty Antarctica has been spared the effects of hunting and fishing. But signs in ice’s cyclical patterns and its biodiversity have become worrying. Connected to the planet’s global ecosystem via atmospheric circulation and ocean currents, this white haven is suffering the effects of human activities. To document and explain what is unfolding in Antarctica, photographer, diver, and marine biologist Laurent Ballesta and photographer of extreme environments Vincent Munier will be blending their artistic perspectives of a rapidly changing continent. Laurent will tackle technical and human prowess below the ice to bear witness to its remarkable underwater life. His photographs will advance knowledge on Antarctica’s unique and little-known biodiversity. On land, his eye riveted to the lens of his camera, Vincent captures snapshots of life in an Emperor Penguin colony.

The city’s founders knew what they were doing: the water’s relentless threat is also the source of the city’s fortune and worldwide influence. But it takes constant vigilance. Over the centuries, Venice has had to invent and innovate, finding new technical solutions to keep the city vital, vibrant, and dry without sacrificing its soul.
