Inside Princess Diana's epic childhood home at Althorp House

Princess Diana grew up at Althorp House in Northamptonshire until she married the Prince of Wales in 1981. The property, which was previously owned by Princess Diana's father Earl John Spencer, is now owned by her brother Charles, the 9th Earl Spencer, and he often shares glimpses inside on social media. It has 90 rooms and 550 acres and is also home to some of the finest European furniture and art you'll ever see. Take a look inside…
