Why is there a forest in SOHO???

Landscape artist Alan Sonfist created Time Landscape as a living monument to the forest that once blanketed Manhattan Island. He proposed the project in 1965. After extensive research on New York’s botany, geology, and history Sonfist and local community members used a palette of native trees, shrubs, wild grasses, flowers, plants, rocks, and earth to plant the 25' x 40' rectangular plot at the northeast corner of La Guardia Place and West Houston Street in 1978.
