So, maybe you've swam in the deep end of the swimming pool, but certainly not one like Y-40 The Deep Joy. Just how deep is it? Well, it measures 21 x 18 meters (69 x 59 feet) and has a maximum depth of 40 meters (131 feet). That's the equivalent of diving the height of a 12-storey building! With specs like that, there's no surprise that it's the world's deepest swimming pool.
Architect Emanuele Boaretto designed the Y-40 for the Hotel Terme Millepini in Montegrotto Terme, Italy, where it was created with the ambition of becoming the “best swimming pool in the world.” It's currently open year round and offers plenty of things to do. Stay at the hotel and partake in scuba diving, free diving, aqua fitness, and other water-centric activities.
