Nothing says summer more than a trip to the pool.

Many of the pools are chock full of history. Eleven Olympic-size pools opened in the 1930s under Parks Department Commissioner Robert Moses. And many are designated landmarks.

We've highlighted five of the most refreshing and interesting city pools here, but there are 56 total to help cool you off as the mercury rises ... and rises.

This year's pool season kicks off June 29, and will be open through Sept. 10. All pools are accessible 11 a.m. to 7 p.m. daily, with a break for cleaning between 3 and 4 p.m.
