"19th-Century Astor Heiress Mansion Listed for $13.75 Million"

Fashion designer Marc Ecko's 19th-century New Jersey mansion, built for an Astor heiress, is on the market for $13.75 million. The 32-acre property, dubbed Stronghold, was designed by architect George B. Post and features a rough-hewn stone facade, bespoke wrought-iron balconies, and a wraparound porch. Ecko oversaw a renovation of the 20,000-square-foot mansion eight years ago, keeping period details while creating a modern, comfortable, and whimsical home. The property includes a carriage house, a basketball court with a modern gym, a pool and lounge area, and several outbuildings.
