Europe and Africa are closer than many people imagine. Only 14 kilometers separate the two continents, a distance so short that, on a clear day, it is possible to see one from the other. This point is located in the Strait of Gibraltar, between Spain and Morocco. It is there that the Mediterranean Sea meets the Atlantic Ocean, forming one of the busiest and most important shipping routes in the world. Over the years, proposals have been made to build a tunnel or a bridge that would connect the two sides. The idea of ​​joining two continents by land is fascinating, but to this day it has never come to fruition. And there is something even more impressive. Some people have already faced the challenge of swimming across this strait. Even with the short distance, the sea currents are strong, the ship traffic is constant and the crossing requires a lot of physical fitness, courage and special authorizations. It is surprising to think that two worlds with so many differences are separated by so little. A natural border that arouses curiosity, admiration and a desire to explore.
