Deepspot in Poland

On Saturday in Mszczonow (near Warsaw) the world's deepest swimming pool at 149 feet in depth opened when it was filled with nearly 2.3 million gallons of water.

Considered a training center for divers the swimming pool, called "Deepspot" is more than twenty times the volume of a standard 25-meter-long pool and features reproductions of underwater caves and Mayan ruins, as well as a small shipwreck that can be explored.

It's really a good place to learn and train in order to dive safely," said Przemyslaw Kacprzak, a 39-year-old scuba instructor who was among those attending the swimming pool's opening.

The swimming pool is also going to be used for training by firefighters and the army.

The construction lasted two years and cost over $9Million.
