What We Do

Designed by Frederick Law Olmsted and Calvert Vaux in the mid-19th century, Prospect Park is Brooklyn’s flagship park, welcoming more than 10 million visits each year.

Prospect Park Alliance is the non-profit organization that sustains “Brooklyn’s Backyard,” working in partnership with the City of New York. The Alliance was founded in 1987 to help restore the park after a long period of deterioration and decline. Today, the Alliance provides critical staff and resources that keep the park green and vibrant for the diverse communities that call Brooklyn home. The Alliance cares for the woodlands and natural areasrestores the park’s buildings and landscapes, creates innovative Park destinations, and provides free or low-cost volunteer, education and recreation programs

Today, Prospect Park is an international model for the care of urban parks, and one of the premier green spaces in the United States.
