'An Impressive Artificial Paradise': Take a Look at the World's Largest Pool — It's Probably Bigger Than You'd Expect

The world's largest swimming pool, completed in 2006, is located at the San Alfonso del Mar resort in Algarrobo, Chile — and calling it big might be an understatement.

The pool, which is estimated to have cost more than $1 billion to construct, is 3,324 feet long, covering near 20 acres. In fact, it is so enormous that it is called a "lagoon," equivalent to about 6,000 standard-size 26 foot long pools, according to GizMag.

According to GizMag, the pool is able to work by collecting, filtering and circulating sea-water. The upkeep costs roughly $4 million annually.

Biochmeist and founder of Crystal Lagoons, Fernando Fischmann, boasted that his company has built "an impressive artificial paradise."

"As long as we have access to unlimited seawater, we can make it work, and it causes no damage to the ocean," he reportedly said.
