Tourists on a river boat make their way along the Canal du Midi in Argens, southwestern France, August 12, 2014, during summer holidays. This 360-km network of navigable waterways links the Mediterranean and the Atlantic Ocean through locks, aqueducts, bridges and tunnels. An UNESCO World Heritage site, the Canal du Midi, built between 1667 and 1694, it is a remarkable feat of civil engineering, paving the way for the Industrial Revolution.
