Check Out This Shot of Princess Diana's Teenage Home, Taken by Her Brother Charles

Followers of the royal family should definitely keep Charles Spencer's Instagram account on their radar.

The 9th Earl Spencer (and Princess Diana's younger brother) is a bestselling author and history buff, who often uses his account to share rare posts that show the longstanding connections between the Spencers and the royal family.

And for those unaware, the earl currently resides at Althorp House, an estate that used to be the Princess of Wales's home. In his latest post, Spencer shared a nighttime shot of Althorp, with a caption that said, “The Stables at @althorphouse tonight, with half a moon overhead.”

Althorp House has been in the possession of the Spencer family since John Spencer purchased it in 1508. The estate was passed down for generations until it was bequeathed to Charles Spencer in 1992.

While the house was never officially owned by the Princess of Wales, she resided there following her parents' separation, when her father won custody of her and moved his family there in 1976. Princess Diana lived at Althorp until she became engaged to Prince Charles in 1981. It is also the site of her final resting place.

The property that Princess Diana called home has been featured in many posts by her brother. Earlier in the spring, he shared an interior shot of the house, saying, “House plants, ready for deployment. #althorp #springflowers.”

Meanwhile, the earl has shown his followers the many majestic animals that roam the grounds of Althorp, including peacocks. In one of Spencer's posts, he wrote: “Tim the Peacock, looking gorgeous in today’s rich sunshine, keeping an eye on the peahens below. #animalsofalthorp #timthepeacock.”
