Nemo 33 of Brussels, Belgium previously held the record of the world’s deepest swimming pool until Padua, Italy’s Y-40 or also known as “The Deep Joy” pool came into the scene.
This Italian creation has a maximum depth of 40 meters, which is 5 meters deeper than that of Nemo 33, is located at Hotel Terme Millepini in Montegrotto Terme, Padua, Italy. The world’s deepest pool was designed by renowned Italian architect Emanuele Boaretto. Y-40 was first built in 1977 before undergoing renovations in 2013.
The pool was then opened to the public on June 5, 2014.
The pool contains over 4.3 million liters of water and contains thermal water making it also possible to dive without the use of wetsuits. Y-40 has platforms of various depths which then eventually plunge into a well like funnel straight down to the bottom.
Some of its main attractions include underwater caves and suspended, transparent underwater tunnels where guests can walk in. Guests can have the option between free diving or scuba diving in the pool.
