The first reported YMCA swimming bath was built at the Brooklyn (NY) Central YMCA in 1885. By the end of the year, it was reported that 17 Ys had pools. Pools then bore scant resemblance to the pools of today: The Brooklyn Central pool was 14' x 45' and 5' deep.
During the early years of the YMCA in New York, the organization was also developing and expanding in Brooklyn and other boroughs. Founded in 1853, the Brooklyn Young Men's Christian Association merged with the YMCA of Queens in 1924 to form the Brooklyn-Queens Young Men's Christian Association. This organization merged with the YMCA of the City of New York in 1957 to form the YMCA of Greater New York.
