Behold, 4 Buckingham Place - home to Lee and Stanislaw Radziwill from 1959 until the early '70s.
The interiors of the eight bedroom, five bathroom home have certainly changed much since those days, when they were stylish decorated by Renzo Mongiardino with rich Ottoman fabrics and grand finishes. But still, the bones of the place, now on the market for £8,750,000, remain - including the ornate fireplaces and peaceful terraces.
Curious to take a look inside Jackie Kennedy's sister's former pad?
