The late Princess of Wales grew up at Althorp House in Northamptonshire until she married the Prince of Wales in 1981, and it was actually where she first met Charles after being introduced by sister Sarah Spencer.
The property, which was previously owned by Princess Diana's father Earl John Spencer, is now owned by Charles, the 9th Earl Spencer, and he often shares glimpses inside on social media.

The Picture Gallery is not the only room in the house that can be used for dinner parties – there is also the Great Room with red walls and a large giltwood mirror, and the Marlborough Room which serves as a formal dining room with space to seat up to 42 guests.
Charles' home also boasts an impressive saloon with a grand wooden staircase, its own billiard room complete with a large pool table, and a library which was described as his favourite room in the house.
