Below its surface lies an entire underwater world.
Designed to resemble a sunken city, explorers can suit up in diving gear to play underwater pool, foosball or chess, or they can just explore the depths of the expansive, multi-themed facility. According to facility owners, it takes several dives to see everything.
The 14 million liters of water — an amount equivalent to nearly six Olympic-sized swimming pools — contain an abandoned city, an apartment, and an arcade. Non-divers can watch friends and loved ones dive from the facility's built-in restaurant.
The pool is currently available by invitation only. It was visited first by the crown prince of Dubai, Sheikh Hamdan bin Mohammed bin Rashid Al Maktoum, and celebrities including Will Smith have documented their dive on social media. The facility is expected to open to the public in late July — and anyone of any experience level can dive, as long as they are 10 years or older.
