During the "Gilded Age" of the late 19th and early 20th centuries, Spring Lake developed into a coastal resort for members of New York City and Philadelphia high society, in similar fashion to the settlements of Newport, Rhode Island and Bar Harbor, Maine. A surviving example of architecture constructed during this era is the Martin Maloney Cottage on Morris Avenue next to the tycoon's former and no longer existent Ballingarry Estate. Another fine example of period architecture listed on the National Register of Historic Places is the Audenried Cottage on Tuttle Avenue.
