The Singapore skyline boasts the largest swimming pool of any other skyline in the world.

The massive pool sits atop the three 55-story high hotel towers of the Marina Bay Sands Resort, an integrated resort property whose construction project was the most expensive of its kind.

The design, conceptualized by the resort’s architect Moshe Safdie, was inspired by a deck of playing cards, appropriate, as one of the hotel’s main attractions is its large casino.

The 475-foot vanishing edge gives the appearance of an abrupt cut-off at 650 feet in the air, however just below the top edge is another trough-like basin which catches the water and returns it to the main pool.

With a length of about three football fields, it takes about 20 minutes to walk from one end of the deck to the other. There is also a restaurant, bar, spa, and botanical garden with 250 species of trees and 650 plants, and an observation deck which costs 20 USDs to enjoy.Please note you cannot swim or relax at the poolside unless you are a hotel guest.
