Located along the Marina Bay waterfront in SIngapore, Marina Bay Sands features three cascading hotel towers topped by an extraordinary sky park. At the top of the 55-storey hotel is a 150-meter infinity swimming pool, the world’s largest outdoor pool at that height. Perched 191 metres above the ground, the pools are made up of 422,000 pounds of stainless steel and can hold 376,500 gallons (1424 cubic metres) of water.
