A piece of mafia history is back on the market. The Staten Island estate built by former Gambino crime family boss Paul Castellano has been listed for $18 million, easily the most expensive home currently for sale in New York City’s outer boroughs. Castellano, who led the Gambino organization from 1976 until his infamous assassination in 1985, commissioned the Todt Hill mansion in 1980 as a towering symbol of power. Today, the 33,000-square-foot residence still commands attention, perched atop the highest natural point on the Atlantic Coastal Plain between Florida and Cape Cod. The 8-bed, 17-bath estate features an array of over-the-top amenities, including a 13-car showroom, indoor and outdoor Olympic-sized pools, a commercial-grade kitchen, solarium, wood-paneled library, elevator, custom Italian fountains, and sweeping views of the Verrazzano Bridge.
