The Prince of Wales followed in his mother's footsteps and visited the Christ the Redeemer statue in Rio de Janeiro.
Prince William stood in the same spot where Diana, Princess of Wales, was photographed 34 years ago.
He is on the third day of a five-day visit to Brazil, where he will present the Earthshot Prize, an annual award for the charity he founded.
The star-studded event will take place at the Museum of Tomorrow in Rio on Wednesday night, with performances from Kylie Minogue and Shawn Mendes and five projects winning £1 million.
The prince is also scheduled to speak at COP30, the UN's annual climate meeting.
On a beautiful day, the future king stood alone and meditated, admiring 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 30 meters high and 28 meters wide with its arms outstretched.
It has become a symbol of hope and resilience and is said to protect the people of Rio.
Princess Diana posed at the same spot in April 1991 during her six-day tour of Brazil with current King Charles III.
As Prince William walked through Rio, dozens of people spoke to him about his late mother, who died in August 1997.
“The prince has enjoyed meeting so many people from all over Rio over the past few days,” a spokesman for the prince said.
“He was incredibly amazed by the number of people who fondly remember his mother’s visit to this beautiful city.”
At the Christ the Redeemer event, Prince William also spent some time away from the cells of the chapel located below the statue.
Security was at a high level throughout the entire trip.
Public access to the statue was temporarily suspended to allow him to visit the site and meet the 15 Earthshot Prize finalists before the evening awards ceremony.
This year's shortlist included the city of Guangzhou in China and its electric public transport network, Lagos Fashion Week in Nigeria, nominated for its work to change the fashion industry, and Barbados for its environmental leadership.
The Prize awards £1 million in grants annually across five different categories to projects aimed at restoring the world's climate.
British Prime Minister Sir Keir Starmer will join the prince for the ceremony before they both travel to Belém in the Amazon rainforest for COP30, where world leaders will discuss how to limit and prepare for further climate change.
Prince William first day in Brazil played soccer at the Maracanã Stadium and barefoot beach volleyball at Copacabana.
On Tuesdaythe focus shifted to the environment – the reason for his visit to the country.
The prince criticized criminals for their involvement in deforestation of the Amazon rainforest during a speech at the United for Wildlife conference.
He also visited the small island of Paqueta, where he met local people, learned about mangrove conservation and planted tree seedlings.
