A few years following the discovery of the isthmus of Panama, Balboa went through the Darien jungle and discovered an ocean that was until then unknown to the Europeans, the American Pacific Ocean, named by them the South Sea. The first city built by the Spanish conquerors in the coast of said sea in 1619 was Panama, later invaded, looted and destroyed by the pirate Henry Morgan in 1671. The city was abandoned and its inhabitants were relocated in another city some kilometers to the West. From that old city remain the ancient architecture of the cathedral, convents, monasteries, public buildings and a bridge, all of them built from stone. Panamá La Vieja has been declared by the Unesco as Patrimony to the Humanity. Tourists may visit the ancient stone buildings and walk through the ancient stone streets which are currently covered by grass. It will feel like a very ancient voyage.
