While Clarence House serves as the official residence of Prince Charles and Camilla in London, the Prince of Wales also has a country home, Highgrove House, which features prominently in season four of The Crown.

Often referred to as Charles and Camilla's "family home," the Georgian neo-classical house dates back to the 1780s, but Prince Charles bought the home and grounds in 1980.

"When the Prince first arrived, Highgrove possessed little more than a neglected kitchen garden, an overgrown copse, some pastureland and a few hollow oaks," reads the estate's website.

According to Andrew Morton's biography of the Princess of Wales, Diana: Her True Story—In Her Own Words, which was written with Diana's cooperation, Prince Charles asked her for help with decorating Highgrove early on in their relationship.

“One of my great joys is to see the pleasure that the garden can bring to many of the visitors and that everybody seems to find some part of it that is special to them.” - HRH The Prince of Wales.
