Halcyon Park is an unincorporated community that was developed by Reverend Cyrus Kemper Capron in Bloomfield, in Essex County, in the U.S. state of New Jersey, in 1895[1] as a planned community of homes with trees and shrubs, picturesque cottages, ponds and common grounds to be maintained by a caretaker and gardener.
Capron envisioned a private residential park for individuals of moderate means to offer all the advantages of the city (proximity to two railroads and a trolley for access to Newark and New York City, water, gas, sewer and paved streets) and the country (trees, ponds, picturesque landscape).
The land was developed with water, sewer and gas lines and paved streets, innovative at the time.
"[5] In 1995, Halcyon Park was added to the New Jersey Register of Historic Places and the National Register of Historic Places as eligible[6] as an "intact collection of early twentieth century residential housing in a planned setting reflecting attention to open space and neighborhood character.
"[7] A report commissioned by NJ Transit in 1995 in preparation for planning the Newark Light Rail Extension into Bloomfield, stated that "Houses within Halcyon Park, built between 1905 and 1930 include a number of well-preserved examples of early-twentieth century residential architecture in Bungalow, American Foursquare, Colonial Revival, Tudor, and Queen Anne styles" and that "Halcyon Park Historic District is eligible for the National Register under Criterion C as an intact twentieth century planned middle-class residential community with a cross-section of the vernacular architectural styles from that period.
