If you are a swimmer and love the depth of the water, then Y-40 Deep Joy in Italy is probably right up your street. This pool reaches a jaw-dropping depth of complete 40 metres that makes it equivalent to a 12-storey building. Not for the weak hearted, the pool reaches a depth of 130ft that is equivalent to the height of a 14-storey building, and is recorded as the deepest indoor swimming pool in the entire world; holding a staggering 4300 cubic metres of water to itself.
This cylindrical pool was designed by renowned architect Emanuele Boaretto. It was opened in June 2014. The pool is filled with 4.3 million liters (1.1 million gallons) of thermal heated water from local springs that allows divers to plunge without the skin unlike in open seas or lakes.
The pool has been constructed in Hotel Millepini Terme in Montegrotto Terme, a small town in Italy, and was designed especially for leisure dives, dive training and photo shoots. It even has special caves, ledges and underwater glass viewing panels for spectators who don’t want to take the risk and get wet. Visitors here can scuba dive, free dive or do aqua fitness sessions at the pool.
