Photographer Diane Arbus didn't actually live in the townhouse itself at 131 Charles Street, but in the carriage house hidden behind it through a narrow, 32-foot-long horse walk. Both the townhouse and the carriage house (address: 131 1/2 Charles Street) are now on the market for $13.5 million. When Arbus lived in the carriage house, in the '60s, it was owned by Thomas B. Morgan, press secretary to Mayor John V. Lindsay and, later, editor of the Village Voice. The house become an individual city landmark in 1966 and is listed on the National Register of Historic Places, and it has been owned since 1968 by Judith Stonehill, an active Greenwich Village historian and preservationist. Unsurprisingly, it has been lovingly preserved and has retained much of its original character, including wide plank hardwood floors, decorative wood moldings, and five fireplaces.
