Why build a massive swimming pool beside an ocean?
Well, the waters of the coast of Chile are very cold and very dangerous that people have been banned against swimming in them. The founder of San Alfonso del Mar resort, Fernando Fischmann, decided to build the resort in 1997 as a way of providing people with a safer environment where they can enjoy water sports and other water activities.
In his mind, the founder wanted a large lagoon, but after traveling the world, he could not find such a technology, he finally came up with this giant pool. The water in the pool is the water from the ocean that is collected, filtered, and the temperature maintained to 9 degrees warmer than the ocean’s water.
