Gouverneur Hospital
Why it's listed
Gouverneur Hospital occupies a full block at 621 Water Street on Manhattan's Lower East Side, an area that long served as the first home of many immigrants. The red-brick Renaissance Revival building is U-shaped, with a central section and two wings ending in curved bays with metal balconies. Terra-cotta quoins and keystones decorate the windows, and a double-story arched window rises above a brownstone entrance. Architect John Rochester Thomas designed it to replace an inadequate 1885 hospital of the same name. Construction began in 1897, and the L-shaped first section opened in 1901, holding nearly three times as many patients as its predecessor. The west wing followed in 1904-1907. A fifth floor replaced the original hipped roof in 1930. Considered the city's most modern and best equipped hospital when it opened, it treated the district's crowded, poor population until 1961. It later housed a school and has since been converted toward apartments.
Significance in brief: The nomination argues it is a major example of the city's concern for medical care of the very poor population of the Lower East Side. When it opened in 1901 it was the most modern and best equipped hospital in the city, and it served the area until 1961. It is also significant as the work of architect John Rochester Thomas.

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.
