Understandably, the interview greatly pleased his father who has worked hard on the royal estate for the last few decades.
"Well, I saw it and I couldn't believe it," Prince Charles admitted in a clip shared by Kensington Palace. "I was deeply touched and moved by what he said."
"Frankly, it reduced me to tears. It did really," he continued. "Because I suddenly thought, well, just hearing that from him has made all the last 50 years worthwhile."
The Duchy of Cornwall is a private estate which was first established by Edward III in 1337 in order to give his son and heir, Prince Edward, some independence.
A charter ruled that each future Duke of Cornwall would be the eldest surviving son of the Monarch and Prince Charles holds the title of the longest serving Duke in history with 50 years beneath his belt.
The estate covers 52,760 hectares of land across 21 counties - extending far beyond Cornwall.
According to the website, Prince Charles' aim is to manage the estate in a "sustainable and financially viable" way before passing it down to Prince William and eventually, Prince George.
The Duchy of Cornwall has become an integral Windsor heirloom, as revenue generated from the property is used to fund the public, private and charitable endeavours of his sons, Princes Harry and William.
