The former Manhattan home of Lady (Mary) Fairfax, widow of the late Sir Warwick Fairfax, is on the market for $US125 million ($119.6 million).
The penthouse atop the Pierre hotel on New York's Fifth Avenue was bought by Lady Fairfax in 1988 for $US12 million.

She sold it in 1999 for $US21.5 million and it had been marketed from 2004-08 with an asking price of $US70 million.
This week, another widow, Barbara Zweig, the wife of the late financier, Martin Zweig, called time on her reign in the Pierre penthouse. Martin Zweig bought the 1115sq m triplex from Lady Fairfax in 1999.
If Ms Zweig's asking price is achieved, it will eclipse New York's residential record by $US30 million (paid for a duplex penthouse under construction at One57 on 157 West 57th Street in December).
Upon settlement in 1988, Lady Fairfax engaged a team of designers, including Frank Grill in Sydney, to revamp the interior and create a grand salon.
Built for $US15 million in 1930 by a joint venture including Charles Pierre Casalasco, the son of a Corsican restaurateur, the 41-storey granite and cream-bricked tower is a landmark above Central Park.
Since the father of French cuisine, Auguste Escoffier, prepared a gala dinner for the opening celebrations, the hotel has been the darling of Manhattan's social set.
After the Depression, it was bought by John Paul Getty for $US2.5 million and in 1959, 75 apartments within the hotel were sold to private residents.
Residents have included Elizabeth Taylor, Yves Saint Laurent and Mohamed al-Fayed.
The penthouse, sometimes called the Chateau in the Sky after its crown of copper mansard roofing, covers three floors.
With four terraces, 360-degree views and a black Belgian marble staircase, it remains one of New York's most exclusive residences.
