Hotel Terme Millepini is a four-star hotel inMontegrotto Terme,Padua,Italy. It contains 100 rooms and until 2020 was recognized for having the world's deepest pool, the Y-40, which put it in theGuinness World Records.[1] The hotel was first built in 1997 and renovated in 2013.[2][3]
Y-40 "The Deep Joy" pool first opened on 5 June 2014 and was designed by architect Emanuele Boaretto. It is 42.15 metres (138 ft) deep, which at the time of opening made it the deepest pool in the world. It contains 4,300 cubic metres (1,136,000 US gal)of thermal water kept at a temperature of 32–34 °C (90–93 °F).[4] The pool features underwater caves and a suspended, transparent, underwater tunnel for guests to walk through. It includes platforms at various depths, ranging from 1.3 metres (4.3 ft) to 12 metres (39 ft), before the walls of the pool narrow into a well-like funnel which plunges straight down to 40 metres (131 ft). The hotel offers tickets tofreedive andscuba dive.[1][5] Italian freediverUmberto Pelizzari first measured the depth before the pool was open.[4]
When it opened on 5 June 2014, it was awarded the "Deepest Swimming Pool for Diving" by theGuinness World Records.[6] That record was previously held by theNemo 33 pool in Belgium.
Y-40 now stands as the third deepest swimming pool in the world, exceeded only byDeepspot inPoland, andDeep Dive Dubai in theUnited Arab Emirates.
The thermal waters originate in deep underground sources at a temperature of more than 40°C. The mineral rich waters are of a salt-bromine-iodine profile having high levels of sodium chloride, bromine and iodine and bromine as well as trace minerals. The water emerges from the source at 87°C similar to other thermal waters in the Euganeo basin. It is cooled before collecting in the soaking pools and swimming pools.[7]
