An elegant 19th-century townhouse owned by the duchess is for sale in central London, priced at $24 million. Located close to Buckingham Palace in the exclusive Belgravia neighborhood, the 6,250-square-foot property was Lily's home ahead of her 2008 wedding to John Spencer-Churchill, 11th Duke of Marlborough (also known as "Sunny" because of his other title of Earl of Sunderland).

Lily kept ownership of the property after relocating to the duke's magnificent ancestral home, the 187-room Blenheim Palace in rural Oxfordshire, around 60 miles northwest of the British capital.

"32 Eaton Place is a wonderful townhouse in the heart of Belgravia," Gary Hersham from realtors Beauchamp Estates says about the five-floor, nine-bedroom home. It also comes with a family kitchen, two kitchenettes, two gardens and a private covered terrace.

"The townhouse provides extensive living space with flexibility if a buyer wanted to use one of the many guest bedrooms as a home study or library for instance," he continues. "With beautiful original details such as ornate fireplaces preserved throughout, this townhouse is of an exceptional caliber."

Lily was the fourth wife of the 11th Duke, who sadly passed away five years ago. The couple met on holiday in Sardinia in 2007 and married the following year when she was in her fifties and the duke – a direct relative of iconic WW2 leader Sir Winston Churchill – was in his eighties.

The home itself forms part of an ornate terrace built by famed Victorian builder Thomas Cubitt from 1826 to 1835.

It features high ceilings and elaborate original cornicing throughout, plus a spacious dual-aspect dining room, and Georgian sash windows overlooking the street.

In an indulgent twist, Lily's principal bedroom suite occupies the entire second floor, with dual aspect windows and a luxury marble-clad en-suite bathroom.
