264 Fifth Avenue
A once-proud brownstone mansion dating to the 1850s, 264 Fifth Avenue was converted to an apartment residence in the late 1870s. Popular with well-to-do bachelors, the building was dubbed The Knickerbocker Flats and housed a fashionable jeweler on its ground floor. The 20th century was less kind to the structure and little remains of 264 Fifth Avenue’s former grandeur save for the still notable round dormers at the attic level, a nod to Parisian fashion on the part of the original builder.
The building may be replaced in the near future by new development.
