Most people know that Lisbon is situated on the shore of the Atlantic ocean, not so widely known though is the fact that the longest river of the Iberian peninsula is floating through the city (well, technically on the side of it). While definitely not a recommandable place to take a swim, a walk at the Tejo (or Tajo as the Spanish say) has it’s merits – particularly for enthusiasts of modern architecture. The Vasco da Gama tower (1,10, last picture) being a prime example. But the most interesting sight, majestic and intriguing at the same time, is the Vasco da Gama bridge (2, 6, 8, 9, 11, 14) . Spanning over 17 km it is the longest bridge of Europe. The slight couverture of the structure allows for interesting photographic angles. I’ll invite you for a walk.
