Prince Charles prepares for the inevitable in the new ITV documentary, Prince Charles: Inside the Duchy, which features Duchy of Cornwall. The heir to the throne "confronts his own mortality" and even "moves into tears" when he thinks his firstborn, Prince William, will be taking over his £1 billion estate.

Prince William is set to inherit his father's property when the time comes. "I've started to think about how I will inherit the Duchy one day and what I do with it," he said. As a preparation, the Duke of Cambridge is now learning about organic farming, building a relationship with tenants, and answering questions about how Brexit will be impacting farm incomes.

In the second episode of the two-part documentary, Prince Charles tackles the transition, passing the Duchy of Cornwall to Prince William. "Confronting your own mortality is a very good thing for you, if I may say so; it's quite good for the soul," he said, via Express, while emotionally watching his son talking to a tenant farmer about the pressures of hill farming.

Prince Charles admits he can't believe his son's dedication to the farm. Hence, he is deeply touched and moved by what Prince William said. It even brings him to tears, thinking that what he heard from his child made the last 50 years of building Dutchy of Cornwall worth every while.

The Prince of Wales builds the property for over 50 years as a source of income to support his family, himself, and charities. The dukedom earned £21 million last year, solely from its diverse property portfolio, including a B&Q site in Milton Keynes.

The first episode features the works of Prince Charles as the longest-serving Duke of Cornwall, who is known as the "boss" by his staff and tenants. It also shows the Duchy headquarters, the struggling farms on the Isles of Scilly, and how farming helps young families.

Since 1952, Prince Charles has been the Duke of Cornwall. Although it has been more than 50 years of serving the Duchy, he still can't believe he made it this far. However, he knows it's a lifetime commitment.

Meanwhile, in a visit at the Duchy farm, according to Daily Mail, Prince William wished he brought his eldest child, Prince George, with him. Kate Middleton's husband knew the younger prince would love the place, as he, too, is obsessed.

While speaking to the farmers, Prince William discussed how important the family is to the estate and the outdoors to his own family. He even revealed that his children are already playing on the tractors, the importance of getting outside, and letting the kids understand nature.
