I couldn’t imagine how deep is the world’s deepest swimming pool. But in order to find out, I quoted the info from wikipedia. It served quite a few purposes for this deepest swimming pool. I love the idea of it being allowed to let outside visitors to look into the pools at various depth level thru the underwater windows.
According to Wikipedia:
Nemo 33 is a recreational diving center in Uccle, Belgium near Brussels that is home to the world’s deepest swimming pool. The pool itself consists of a submerged structure with flat platforms at various depth levels. The pool has two large flat-bottomed areas at depth levels of 5 m (16 ft) and 10 m (32 ft), and a large circular pit descending to a depth of 33 m (108 ft). It is filled with 2,500,000 liters of non-chlorinated, highly filtered spring water maintained at 30 Â°C (86 Â°F) and contains 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, and opened in 2004.
