Strike it rich! Stunning East Sussex country mansion once owned by US born gold prospector Sir Harry Oakes 'who hid treasure in its walls' before being brutally murdered goes on market for £3.5m

A stunning East Sussex mansion once owned by US born gold prospector Sir Harry Oakes before he was brutally murdered has gone on sale for £3.5million.    

Oak Hall in Heathfield was built in the 19th century and Sir Oakes was widely rumoured to have stashed treasure in every property he owned.  

While the true amount is unknown, Oakes was estimated to have been worth £150million before his death - equivalent to around £1.8billion today. 

The property went on to become a school for a brief period but returned to being a private residence in the 1980s.

Despite this, the treasure has never been found, and rumours of its existence still circle the home.

With 53 acres of grounds on the estate, there are plenty of opportunities for eager treasure hunters to search for the secrets of the manor.

The 11-bedroom property features several eye-catching elements - such as the oak panelled drawing room and the dining room with a stunning marble fireplace.

The four-story home also includes a one-bedroom staff apartment on the second floor, and a tower with a roof terrace.

The property has everything one might need from a kitchen with a four oven Aga for any eager cooks to a library with fitted bookshelves for keen readers.

The once in a lifetime property is currently listed with Savills for £3,500,000.

In 1935, Oakes relocated to the Bahamas for tax reasons, where he became close friends with Edward VIII, Duke of Windsor and Nazi sympathiser. He remained in the Bahamas for nearly a decade, until July 8, 1943 when he was late for his round of golf with the Duke, prompting a short search for the prospector.
