The first example in New England of a landfill redeveloped for public recreation, Danehy Park provides three soccer fields, three softball fields, a par course, other specialized play areas, and 2.5 miles of walking and jogging paths set on a fifty-acre site planted with more than eight hundred trees. Originally an industrial area for brickyards, drying kilns, and clay pits, the site was acquired by the City of Cambridge in 1952 and used for dumping until 1971. The MBTA next added fill from subway construction, occasionally to a depth of forty feet. Environmental monitoring began in the early 1980s. Project designer John Kissida worked with public artist Mierle Laderman Ukeles to create a half-mile-long “glassphalt” path (crushed glass and mirror material, emphasizing the recycled nature of the site) that provides dramatic views of the Boston skyline.
