Yes, it’s true, this is not a Photoshopping illusion. According to the Guinness Book of Records, the above body of water is a made made swimming pool at the San Alfonso del Mar in Chile.
It is 1,013 m (3,324 ft) long and has an area of 8 ha (19.77 acre), it was completed in December 2006. The lagoon, cost an estimated $US1.5 billion to build, covers an area of eight hectares and the 2.5 million litres of water needed to fill it is drawn from the Pacific Ocean. It costs over $US2 million a year to maintain and uses a computer-controlled filtering system that sucks sea water in one end, filters it, and then blows it out the other end. Since the pool is so huge resort guests make use of kayaks and small boats to move around.
I’m just glad I don’t have to be the one to maintain it!
