Originally named Leverett Park, in 1900 it was renamed to honor its designer, Frederick Law Olmsted.Olmsted Park can be roughly divided into two parts. In the south, bordering Jamaica Pond, it includes athletic fields and three ponds: from the south, a small kettle pond called Ward's Pond, the tiny Willow Pond, and the much larger Leverett's Pond.
