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.

In the heart of Paris, Île de la Cité once featured one of the most majestic palaces of medieval times: The Palais des Rois. Built in the early Middle Ages, only two parts of this grandiose palace remain: The Sainte-Chapelle, the largest and most daring palatial chapel of the time; and the Conciergerie, a medieval room of impressive dimensions, known for having served as a prison and housing the jails of Marie-Antoinette.

Looks at the engineering of the Knights Templar, the religious order that marked the rise of the Middle Ages, and their amazing buildings in the west of Europe.

In the heart of central Europe are some of the world’s most impenetrable military strongholds. In France, 160 megastructure fortresses still line the country’s borders 3 centuries after they were constructed. As solid as ever, how did they withstand attack after attack? Was the secret in their materials? Their shape? In fact, the strength and resilience of these megastructures is due to the genius of one man: Sébastien le Prestre de Vauban.
