Mrs. O.H.P Belmont Residence, ca. 1910. This neoclassical three-story townhouse was designed by the architecture firm of Hunt & Hunt for Alva Belmont and her second husband Oliver Belmont (though he died before the home was finished). Following her husband's death, she commissioned an additional wing on the home to house his collection of medieval and early Renaissance armor. The Armory as the large gallery was known hosted women suffragists events during Alva's later progressive years. She sold the home in 1923 (the armor collection went to the Metropolitan Museum). The Catholic Charities of the New York Archdiocese later occupied the mansion. The Archdiocese sold the building to a developer in the early 1950s who demolished it for a 23-story office building designed by Kahn & Jacobs.
