The prince is also scheduled to give a speech at COP30, the UN’s annual climate meeting.
On a picture perfect day, the future king stood alone in a moment of reflection as he took in the views of Rio de Janeiro from the top of Mount Corcovado where Christ the Redeemer stands.
The iconic and imposing statue is one of the largest Art Deco sculptures in the world, standing at 30 metres tall and reaching 28 metres wide with its outstretched arms.
It has become a symbol of hope and resilience and is said to protect the people of Rio.
Princess Diana posed in the same spot in April 1991 during her six-day tour of Brazil with the now King Charles III.
During Prince William’s walkabouts in Rio, dozens of people spoke to him about his late mother, who died in August 1997.
“The prince has loved meeting so many people from across Rio over the last few days,” said a spokesperson for the prince.
“He’s been incredibly struck by the number of people who fondly remember his mother’s visit to this beautiful city.”
At Christ the Redeemer, Prince William also had some time away from the cameras in the chapel that sits beneath the statue.
Security has been high throughout his trip.
Public access to the statue was temporarily suspended to allow him to visit the site and meet the 15 Earthshot Prize finalists ahead of the evening’s awards ceremony.
