It was built in 1902-06 and designed by C.P.H. Gilbert.","why_significant":"The nomination presents it as one of the most elegant French Beaux-Arts residences in New York City. It is also a reminder of the time when Murray Hill was a fashionable residential district. It recalls the scale and elegance of the limestone mansions that once lined upper Fifth Avenue, and it is the work of the noted architect Charles Pierrepont H. Gilbert.","narrative":"Built from 1902 to 1906 at 233 Madison Avenue, this limestone mansion occupies the northeast corner of Madison Avenue and East 37th Street in Manhattan's Murray Hill. Architect Charles Pierrepont H. Gilbert designed it in the French Beaux-Arts style for Joseph Raphael DeLamar, a Amsterdam-born businessman who made a fortune in Colorado gold and settled in New York in 1888. The 37th Street facade is divided into three parts, with projecting end pavilions, rusticated lower floors, and paired windows. Its most striking feature is a great mansard roof with copper crestings decorated with shell motifs. Inside are an elliptical staircase beneath a stained glass skylight, painted and gilded ceilings, and paneled rooms. The National Democratic Club bought the house in 1923 for its headquarters. The Polish government purchased it in 1973 and has restored much of the interior. The house is valued as a surviving example of the grand residences of its era.","period_of_significance":"1900-","architect_builder":"C.P.H.
