Princess Diana's brother took to Twitter, where he posted a photo taken in the entrance of the stunning building.
The image showed a large display of blossom branches in a beautiful ornate vase sitting on a carved white table.
Large paintings were just visible on the walls and a marble bust stood in the left corner.
The Earl captioned the picture: "A spring flourish in the entrance hall at @AlthorpHouse today. #cherryblossom."

Charles is custodian of the estate in Northamptonshire and often shares photos of seasonal changes to the inside and outside of the property, which has been in the Spencer family for hundreds of years.
His followers soon complemented the latest addition, with one replying: "That’s beautiful! It’s perfect with that vase."

Another agreed, responding: "Pretty little cherry blossoms sir, and loving the table and vase."
A third commented: "I can't wait to visit next summer," while a fourth simply wrote: "Beautiful xxx."
As well as posting photos from in and around Althorp, the father-of-seven sometimes shares previously unseen pictures of his family.
On Mother's Day earlier this month, for example, he posted a black-and-white snapshot of his late mother, Frances Shand Kydd.
In the picture, she smiled as she looked down adoringly at the sleeping baby in her arms.
