The deepest swimming pool in the world was opened in 2004 in Brussels, Belgium. In fact, it's a Recreational Diving Center, called Nemo 33. The swimming pool floor consists of flat platforms at different levels. The pool has two large flat-bottomed areas at depth levels of 5m (16 ft) and 10m (32 ft), and a large circular pit of 33m (108 ft). It also contains several underwater caves at the 10m depth level. The Center was designed by Belgian diving expert John Beernaerts as a facility for instruction, recreation and film production.
