The palace born for a self-made millionaire's patronage

Spencer House, constructed in 1754, is a recognized architectural landmark residing in the St James's district of London. Conceived by John Spencer, who later ascended as the first Earl Spencer, the residence was fashioned under the artistic guidance of John Vardy, with James 'Athenian' Stuart later contributing to the creation of a palatial neoclassical-styled mansion. The grand staterooms of the house served as a stage for London's high society, hosting a diverse collection of renowned personalities throughout its existence.

Self-made millionaire Barney Barnato and the Marlborough family left their mark, welcoming their firstborn child within its grand halls. However, the Spencer family vacated the residence during the late 1940s, leaving it to be restored by RIT Capital Partners. The mansion, a treasure in the ownership of the Earls Spencer, continues to stand as a testament to the era it graced till this day.
