Right in the heart of the Big Apple is this magnificent mansion designed by William Tuthill, the architect of Carnegie Hall. Stepping into this mansion is like stepping into a world of wealth and power from turn-of-the-century New York. Built in 1909, this free-standing Manhattan mansion has been designated a national, state and city landmark. The tobacco baron who built it even had an underground tunnel (now boarded up) that connected the home to both Riverside Park and the Hudson River. At 12,000 square feet and four stories high, who says you can’t get a decent-size house in Manhattan? If you have $25 million.
