Allegra’s Wacky Facts: World’s Largest Pool Cost Over $1 Billion and Holds 66 Million Gallons of Water!


The San Alfonso de Mar resort in Chile has constructed the world’s largest pool which holds 66 million gallons of crystal clear sea water. The pool required 5 years of construction and was opened in 2006 after the resort shelled out $1 billion to complete the project! The pool also requires over $2 million a year to keep it in working order!

It is approximately the length of 20 Olympic size swimming pools at three-fifths of a mile and draws water from the ocean which continuously cleans the pool. It also holds the Guinness record for the world’s deepest pool at 115 feet so hitting the bottom is a non-issue when attempting cannon balls here.

A computer controlled suction and filtration system sucks water in from the ocean at one end and pumps it out at the other while the sun warms the water to a temperature nine degrees higher than the sea.

The second largest pool lags behind this gigantic construction; the Orthlieb in Morocco measures 1,575ft long. This pool is more than double that size!
