"Baseball had nothing to do with the naming of Fenway Park: The stadium gets its moniker from the nearby Back Bay Fens, a stretch of saltwater marsh in the heart of Boston that was landscaped into a park by Frederick Law Olmsted. The Fens are among the wilder parts of the Emerald Necklace, 1,100 acres of parklands running from the Charles River to Brookline that include familiar spaces like the Boston Common and Boston Public Garden but also less-traveled (by visitors, anyway) sections like Olmsted Park, Jamaica Pond, the Arnold Arboretum , and Franklin Park. The arboretum, part of Harvard University and established in 1872, is one of Olmsted’s most unaltered terrains, with paths running up and around 261 acres of woodland interspersed with a curated collection of trees, plants, shrubs, and vines native to New England."
