Y-40, Indoor swimming center in Montegrotto Terme, Italy.
Y-40 is a diving center in Montegrotto Terme that features an enormous pool filled with thermal water at comfortable temperatures. The facility includes diving platforms of different heights and underwater structures designed for training and exploration.
The center opened in 2014 as a new diving facility designed by architect Emanuele Boaretto. The project involved careful planning to create a safe and functional space for underwater training.
The facility draws divers from around the world and serves as a hub for underwater training and skill development. People come here to practice techniques and explore diving in a controlled setting away from ocean conditions.
The center is located inside Hotel Terme Millepini and is easy to reach when exploring the area. Visitors should be in reasonable physical condition and ideally bring some swimming or diving experience.
A glass tunnel runs through the water where visitors can walk and watch divers at work below. Several artificial caves inside the pool allow specialists to practice cave diving techniques.

A list of unique natural swimming pools and basins has been compiled. Some are bold architectural constructions, others are the result of geological phenomena. Some are located in luxury hotels, others are accessible to the public. What makes these sites particularly interesting is their diversity: there are pools hanging at several hundred meters altitude overlooking cities, geothermal basins fed directly by volcanic activity, a 40-meter deep diving pool in Italy, and even a natural basin formed in rock on a Greek island. There are also recent installations that push engineering boundaries as well as historic sites used for nearly a century. Whether you seek relaxation in thermal waters or swimming with panoramic views, this selection provides a good overview of what exists.
