The Prince of Wales was pleased to see how he overcame the endless criticism of those who doubted some of his once-controversial methods.

The 70-year-old unveiled his thoughts in a two-part documentary commissioned by ITV to mark the 50th anniversary of the Duchy of Cornwall.

He also hinted that it was time for new blood when his eldest son, Prince William, prepared to inherit the Duchy someday.

The documentary accompanies Charles to every corner of the estate – from family businesses to the Scilly Isles and his model village of Poundbury in Dorset.

Charles said the idea behind Poundbury is to build a church rather than a "different housing estate." He acknowledged, however, that she met with criticism.

"Everyone was against it and in the end I was determined to hold on to my weapons.

"I wanted to make sure that … we are more sustainable this time," he said in the ITV documentation.

He hopes to be alive to see the completion of the village project in Poundbury so he can look back and reflect on his efforts.

However, the criticism of the Duke was not limited to the Poundary project during his term.

He was also scrutinized 35 years ago when he started organic farming and focused on the "long-term".

"It was an unusual thing that, as you can imagine, has attracted a lot of attention," he said.

The farmers are the heart of the Duchy with around 700 agricultural leases within the estate.

Charles notes that during his time as a Guardian, he watched younger generations take over family businesses as he assumed the office of Duke after the Queen's accession to the throne.

He said, "For me, the miraculous is the connection between my family and their families."

The prince had previously been described by Alastair Martin, the Dictyant of Cornwall, as "very practical" in his role.

Mr. Martin will be responsible for the preparation of the Duke of Cambridge, who will one day inherit the estate from his father.

Charles said his eldest son had time to prepare for his upcoming assignment.

He added, "He's pretty lucky because I was there at 21.

"I really had a bit of a baptism of fire.

"He visits various parts of the Duchy of Cornwall and learns, I hope, over time."

Prince William briefly appears in the documentary, saying that he's been thinking about how he'll inherit the Duchy.

"Rest assured, I will not rock the boat. I'm doing almost the same thing as my dad, "William said.

Prince Charles's wife, the Duchess of Cornwall, also appears in the program, revealing the importance of the estate to the prince.

"It's not just a business, I think it's all about what he's passionate about," she said.

The duchy was founded by Edward III to give his son and heir, Edward, later known as the Black Prince, a private income. Its purpose is the same to this day.

The property is a private property, investment and real estate portfolio – including the Kennington Oval Cricket Grounds and 67,000 acres of Dartmoor.

The first episode will air on Thursday, October 24, at 9:00 pm on ITV.
