4. Astoria Pool

The largest pool on our list–and in New York City–is the Astoria Pool in Queens. The Art Deco/Art Moderne-influenced pool stands as a beacon to the days of Robert Moses‘ New York. Under Moses and Mayor Fiorello H. LaGuardia‘s leadership, eleven public pools were erected around the city. On the day of the pool’s opening in 1936, Olympic trials for the U.S. team were held, followed by trials again in 1964. More photos of how this pool looks today, here.
