Princess Diana grew up at Althorp House in Northamptonshire, a vast country house that is so luxurious it could rival a royal residence.

The stately home was even where she first met the Prince of Wales, when Charles was introduced by Diana's sister, Sarah Spencer.

Althorp House was previously owned by Princess Diana's father, Earl John Spencer, and is now home to her brother, Charles, the 9th Earl Spencer, who often shares glimpses inside its lavish walls on social media. With 90 rooms, 550 acres of land and a special temple dedicated to the late Princess, who is buried there, it is as spectacular as you would imagine. Take a look around…
The incredible exterior of Althorp was seen in a recent Instagram post shared by Earl Spencer, who wrote: "Cool July evening air, at @althorphouse." The vast number of windows give an indication of its size, and it is surrounded by pristine gardens.
Charles revealed the previously unseen falconry in the grounds of Althorp in June, revealing that it had been built for one week's entertainment in 1613.

It features an oak bed, and 'S''s embroidered on the curtains to represent the surname Spencer.
