From Haussmannian buildings to half-timbered houses in Alsace, we will introduce ourselves to all styles of architecture. We will discover the contemporary art of stained glass in Troyes, observe the all-military rigour of Vauban in Saint-Malo and walk along the quays to the Ile de la Cité to discover Old Paris. In the heart of the waste heaps in Lens or Lille, we will feel the heartbeat of the mines. Finally, we will admire the architectural prowess of the Millau viaduct, from above and below.
