Nemo 33 is the world's deepest indoor pool. The pool is located in Brussels, Belgium. Its maximum depth is 34.5 meters (113 ft), the pool consists of two large flat-bottomed areas at depth levels of 16 ft and 32 ft, and a large circular pit descending to the maximum depth of 113 ft. It contains 2.5 million liters of non-chlorinated, highly filtered spring water maintained at 30 °C (86 °F) and holds several simulated underwater caves at the 10 metres (33 ft) depth level. There are numerous underwater windows that allow outside visitors to look into the pools at various depths." And it apparently costs roughly $28 US Dollars for a dive? Must. Go. Diving!!
