The Duke of Edinburgh declared himself to be "the world's most experienced plaque unveiler" as he officially opened a school garden in County Durham.
Prince Philip made the trip to Langley Park Primary School in County Durham by helicopter and was greeted by cheering children and parents.
The Duke came to open the school's Royal Garden, which has been completed by pupils and volunteers.
After being given a tour he was asked to unveil a plaque, and turned to the children and said:
"Pay attention, you are about to see the world's most experienced plaque unveiler."
He was also presented with a book compiled by the children as well as a lamp, which he said would be useful to him in the dark.
The visit was arranged after a teacher at the school wrote to the Duke and asked if he would visit.
"It's a huge thing for the local area and the school to get someone from the royal family up here.
"The kids loved to see him and locals have come out to show their support so it's been fantastic."
