A
rare piece of Gilded Age history is returning to the market, with a stunning Upper East Side apartment hitting the market for $6 million. Located on East 73rd Street, this opulent residence occupies the second floor of Joseph Pulitzer's former mansion, designed by Stanford White in the style of a 17th-century Venetian palace.

    Pulitzer, the pioneering journalist and namesake of the Pulitzer Prize, lived in the home for its final eight years. The mansion was built with cutting-edge features for its time, including soundproofing measures like triple-pane windows and ball bearings under the floors to block out city noise.

    The building was converted into 17 individual residences in the 1930s and restructured as a co-op in the 1950s. This particular two-bedroom apartment is being sold by an 84-year-old former Tiffany & Co. accessory designer who has spent much of her retirement living there with her dog.

    The residence retains many of its original details, including deep oak millwork and soaring 19-foot ceilings. The main living area features oversize windows, a fireplace, and a dramatic stone-column stairwell. A unique feature is the two-story bathroom with a staircase leading to a sunken soaking tub. A terrace runs along the length of the apartment, offering views of 73rd Street.

    For buyers seeking even more grandeur, the building's penthouse – complete with its own squash court – is also currently for sale.
