The pool shown below is at the Marina Bay Sands, the world's most expensive hotel in Singapore
It's the world's largest outdoor pool built on the 55th floor of this swanky hotel.
The infinity pool on the roof is in the 'SkyPark' which spans the three towers of the hotel.
The platform itself is longer than the Eiffel tower laid down and is one of the largest of its kind in the world.
Infinity pools give the effect that the water extends to the horizon.
In reality, the water spills over the edge into a catchment below, and is then pumped back into the pool.
