River boats with tourists make their way near others moored in the harbour of Le Somail along the Canal du Midi, 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, is a remarkable feat of civil engineering, that paved the way for the Industrial Revolution.
