Located in brussels, belgium is ‘Nemo 33’ The world’s deepest indoor swimming pool. This diving pool is a mecca for both professional and recreational divers, with a depth of 33 meters (108 ft) at its deepest point and contains around 2.5 million litres (550,000 gal, 4.4 million pints, 660,000 US gallons) of water. The facility, which opened in June 2004, is used for dive training, leisure diving, and research.
The water is kept at a constant 30 degrees Celsius (86 degrees Fahrenheit) thanks to a large array of solar panels, and features numerous simulated underwater ‘caves’ for exploration and three air-filled diving bells that enable diving instructors to communicate with their charges without returning to the surface. There are two ‘basins’ and three ‘pits’, the deepest of which is 6 m (19 ft 7 in) across and drops to 33 m (108 ft).
Various submerged windows are throughout the facility encouraging outside visitors to look into the structure at different depths. The adjoining restaurant and bar offers peeks into the pool via windows.
The facility was designed by Belgian expert diver John Beernaerts, an idea that was spurred by Beernaerts’ desire to mimic the conditions of bora bora in his home country, achieving this through three years of study and testing 21 versions. the outcome was a multi-purpose diving instruction, recreational, and film production complex.
