Why it's listed
Built between 1858 and 1870 on Welfare Island in New York City, this hospital was designed by James Renwick, Jr. to replace an earlier hospital destroyed by fire in February 1858. Plans were accepted that March, and the goal was the largest and finest hospital ever erected in America. The building has been known as Island Hospital, Charity Hospital from 1866, and City Hospital from 1892. Its walls are random ashlar granite quarried on the island by inmates of the Island Penitentiary, who also worked on construction. A long main block is crossed at the center by a tall mansard-roofed pavilion, with transverse wings at each end. Rusticated arched doorways, small octagonal stone frames, dormers with triangular pediments and a balustraded double staircase leading to the second floor are its focal features. Renwick's main building at Vassar College, built at about the same time, closely resembles it. The building is currently unused pending restoration.
Significance in brief: The nomination argues it is significant as a major work of architect James Renwick, Jr., intended to be the largest and finest hospital in America when planned. Its mansard-roofed central pavilion, granite walls and monumental double staircase are noted as architectural features. It also reflects the 19th-century building practices of Welfare Island, using local granite quarried by penitentiary inmates.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
Noted as vacant in the nomination. Nomination documents can be decades old; current status may differ. If you are considering buying an empty listed property, read the due-diligence checklist.
