Central Park in New York was built between 1857 and 1876 on land that included Seneca Village, a community of about 225 people that was cleared in 1857. The park's neighbouring properties now carry a measured price premium.

What happened

The record, in order.

Central Park was built between 1857 and 1876 on 341 hectares in Manhattan. The land cost was reported as about USD 5 million. A claim that total cost was USD 14 million could not be confirmed from a primary source.

The site included Seneca Village, a community of about 225 people, about two-thirds of them African American and about half of those homeowners. It was cleared by expropriation in 1857. Secondary sources give an average payment of about USD 700 per lot. Gotham Gazette reported that about 1,600 people in all were displaced from the park area.

Rosenzweig and Blackmar, cited by the Central Park Conservancy's history page, recorded that in 1853 the land was not considered suitable for private development and that there were no skyscrapers.

Frederick Law Olmsted argued for the park partly on property value: he calculated that the value of three surrounding districts rose from USD 26.4 million in 1856 to USD 236 million in 1873. the sources reviewed notes there is no comparison with a no-park case.

In 2009 an Appleseed report found properties within three blocks of the park carried a premium of about 18%, totalling USD 17.7 billion, or 8.1% of Manhattan real-estate value. A 2015 report commissioned by the Central Park Conservancy put the figure above USD 26 billion. The Conservancy supplies about 80% of the park's operating budget; in fiscal 2025 it reported revenue of USD 172.9 million and net assets of USD 669.4 million, with 42 million visits a year.
