Hamilton Fish Pool, 1936.

Designed in 1898 by Carrère & Hastings (of later NYPL building fame) the Hamilton Fish Park Gymnasium opened in 1900. The building, a grand Beaux Arts structure, was constructed as the first phase of the park's construction, and had only a small fountain and grassy area with benches surrounding it. In 1903 more recreational venues were constructed including tennis courts and a running track. In June of 1936 the WPA pool opened adjacent to the elaborate gymnasium. In 1952 the U.S. Olympic Team used the pool for practice sessions before the Helsinki Olympics.

Hamilton Fish Park (named for a 19th century New York politician) underwent a $14 million restoration in the early 1990s, including upkeep on the pool. The gymnasium was granted landmark status in 1982 and is today used as a community center.
