The world's deepest swimming pool is set to open in Poland, with a depth of 148 feet and a water volume equivalent to 27 Olympic-size swimming pools.
DeepSpot will open its doors to the public in autumn of this year in the central Polish town of Mszczonow, about 40 kilometres from the capital Warsaw.
It will be accessible to everyone, not only scuba divers, and will include an underwater tunnel, hotel rooms overlooking the pool, as well as restaurants and conference rooms.
DeepSpot is reportedly being constructed by the same company who built the popular indoor skydiving simulator FlySpot in Poland's Warsaw West County.
According to local media, 8,000 cubic metres of water will be required to fill the pool - or the equivalent of 27 82-foot swimming pools.
However, the impressive pool will only hold the record as the world's deepest for about six months until the Blue Abyss, currently under construction in Colchester in the UK, opens with a 164-foot-deep pool.
The Blue Abyss is intended to be a deep sea and space research, training and test facility, whose primary function is to enable extreme environment development - both human and robotic.
According to local media, DeepSpot will be 16 feet deeper than the present record holder - Y-40 Deep Joy in the northern Italian town of Montegrotto Terme.
That incredible swim centre, designed by renowned architect Emanuele Boaretto, is located within the four-star Hotel Terme Millepini.
Visitors, enjoying a regular temperature of between 32-34Â°C, are able to use the facilities for free diving and scuba diving, with underwater caves for cave diving beginners.
There is also a unique suspended underwater tunnel which is entirely transparent, so non-swimmers can experience the pool without getting wet.
Before Y-40 Deep Joy's completion on June 5, 2014, the record was held by the Nemo 33 facility in Brussels, Belgium.
Famous for its deep pit, the Nemo 33 pool measured 113 feet - 35 feet less than DeepSpot.
It will be the deepest pool in the world, but just how tall is 148 feet?
It is taller than the Christ the Redeemer statue towering above Rio de Janeiro in Brazil, which measures 125 feet.
It is around half the size of the Statue of Liberty in New York, minus the pedestal, which measures around 305 feet.
It the height of 27 men of average height standing one on top of the other.
At least six of these pools could fit underneath the Eiffel Tower, which stands at 984 feet.
