Earlier in the second day of their four-day visit to the country, the couple spoke to schoolchildren in Spanish as they took part in an art session and planted trees during a visit to a school.
At the Colegio La Giralda, the couple’s arrival was celebrated with performances from pupils who wore traditional Colombian dress and performed cumbia songs with live percussion.
While visiting a nursery class, the Duchess told a student in Spanish: “You’re the same age as my son Archie.”
The Duke also practised his Spanish, asking students their names and ages.
Harper’s Bazaar magazine, covering the trip as the only words pool, said the children performed a song for the couple before presenting them with gifts and handwritten letters.
The couple have a full security detail during their visit, alongside Ms Marquez, who invited them to Colombia for what has been dubbed a DIY royal tour.
They also visited the school’s “social and emotional gym” which teaches students mental and physical exercises to balance their mental health and personal wellbeing.
