In the South American resort of San Alfonso del Mar in Chile, this artificial lagoon, acknowledged by Guinness World Records as being the world’s largest swimming pool. Over one kilometer long, 8 hectares in surface and 2.5 million liters of water. Too big to picture? Let’s put it this way: the size of the lagoon is equivalent to 6,000 regular, 8-meter long swimming pools. The revolutionary clear water artificial lagoons, transparent to a depth of 35 meters and unprecedented in design and construction methods, are the brainchild of Crystal Lagoons founder, biochemist and Chilean businessman Fernando Fischmann.
