Worlds Biggest Swimming Pool
I’m quite a keen swimmer - but this had me rubbing my goggles.

The worlds biggest swimming pool, San Alfonso del Mar is 1km in length and 10 times longer than the previous Guinness world record holder in Morroco. The revolutionary clear water artificial lagoon, 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. Equivalent in size to an incredible 6,000 standard domestic pools, details of its technology are to be unveiled for the first time at Cityscape Dubai later this month.
