John Kellum designed it in 1858, and it was essentially completed in the 1880s under Leopold Eidlitz.","why_significant":"The nomination presents it as an outstanding example of the 19th-century Anglo-Italian style and one of the city's finest surviving monumental civic buildings of that era. It is also a tangible link to the Tweed Ring, whose graft inflated construction costs from a planned $250,000 to more than $13,000,000. Its architecture links City Hall, the Surrogate Court Building and the Municipal Building.","narrative":"Tweed Courthouse, at 52 Chambers Street, sits at the northern end of City Hall Park in Manhattan. Granite bearing walls with iron framework are sheathed in white Massachusetts marble. Though modest in size at about 150 by 250 feet, it reads as monumental thanks to a tetrastyle Corinthian portico, two-story pilasters over a rusticated base, and a balustraded roofline. Inside, two intersecting halls meet at an octagonal well topped by an iron-and-glass domed skylight. John Kellum designed the building in 1858, and Leopold Eidlitz added a south wing and renovated interior portions in the 1880s. Construction became notorious under Boss Tweed's ring, which turned a $250,000 appropriation into more than $13,000,000 in spending, much of it fraudulent. The listing rests on two points: the building is a leading example of Anglo-Italian civic architecture, and it stands as a physical reminder of a remarkable period in New York municipal politics.","period_of_significance":"19th Century","architect_builder":"John Kellum (original design, 1858); Leopold Eidlitz (south wing and interior renovation, 1880s)","architectural_style":"Anglo-Italian (Renaissance palace type) with Corinthian portico","criteria":[],"status_note":"Listed as in good condition, altered, on its original site, owned by the City of New York and in government use.
