Following the opening of a fully transparent swimming pool in London, we roundup eight spectacular see-through pools from around the world.
This 25-metre-long pool projects from the front of the Hotel Hubertus at a ski resort in the Italian province of South Tyrol.
Supported 12 metres above the ground by native larch trees that have been stripped of their bark, the pool has a glazed opening in its underside to give swimmers "the feeling of floating".
Connecting two buildings on the 10th floor within the Embassy Estates development in London, the Sky Pool is described by architecture studio HAL as the world's first fully transparent pool.
The swimmable bridge is fully constructed from transparent acrylic so swimmers can see views of London and the ground 35 metres below.
This house in Marbella by Dutch office Wiel Arets Architects is built below a rooftop pool that cantilevers from the home.
The glass-bottomed pool projects out across a semi-enclosed terrace that has a rippled light effect from the water above.
Designed by Chicago-based studio Solomon Cordwell Buenz, the Anaha complex in Honolulu, Hawaii, includes a glass-bottomed pool that cantilevers out from the building's seventh floor.
The transparent base allows swimmers to look down at the ground 23 metres below.
Fernanda Marques designed the Panorama apartment around an aquarium-like swimming pool.
The 10-metre-long swimming pool is separated from the apartment's main living area by thick glass panels so that swimmers appear on display in the room.
A glass-sided rooftop pool visible from the street tops this concrete home designed by Architrend Architecture in Malta.
The pool sits above the house's entrance lobby, and a glass panel in the base of the pool allows light into the space and lets people in the home see the swimmers above.
The Market Square Tower skyscraper in Houston is topped with a cross-shaped pool that extends over the side of the building.
Built on the development's 40th floor, the glass-bottomed section is cantilevered from the skyscraper 153 metres above the ground.
Set on the top floor of a hotel in Rio de Janeiro, this pool has a glass front so that swimmers can enjoy views of the city's famous Copacabana Beach.
The rooftop pool was designed by Oppenheim Architecture and Studio Arthur Casas for the Emiliano Hotel.
