Nemo 33 is the deepest swimming pool in the world. Its maximum depth is 35 meters. It contains 2,500,000 liters of non-chlorinated, highly filtered spring water maintained at 30 °C and holds several simulated underwater caves at the 10 m depth level. There are numerous underwater windows that allow outside visitors to look into the pools at various depths. The complex was designed by Belgian diving expert John Beernaerts as a multi-purpose diving instruction, recreational, and film production facility.
