New York City New Deal...

1939 World's Fair Aquacade

Billy Rose's Aquacade in Flushing Meadow Park, Queens, star of the 1939-40 World's Fair, 10,000 seats looking down on a pool "big enough to fit 1,750 tons of water (when there's that much water, gallons ain't gonna cut it)... Synchronized swimming bathing beauties... [Billy Rose was] the 'aquatic Busby Berkeley'"[4]. It was designed by architects Sloan & Robertson in 1936, with several last-minute changes by Billy Rose in 1939[7]. Thus the Aquacade itself was not a New Deal project, except insofar as it sat on land prepared and an infrastructure prepared for it by the WPA (and unless WPA labor was involved in building it).

The amphitheatre was meant to be a permanent adornment for the park. After the fair the site was converted to the New York State Marine Amphitheater by the Parks Department with New Deal funding, the architect was Aymar Embury II[3]. It served as a public swimming pool as well as an entertainment venue — light towers, control booth and 9,000 seats left intact — for many years, including the 1964-65 World's Fair, and later renamed the Gertrude Ederle Amphitheater after the English Channel swimmer who grew up in New York and also performed at the Aquacade. Over time the facility fell into disrepair; the pool was closed in 1977 and the entire amphitheater was demolished in 1996[1,2].
