The Duchess of Cornwall returned to her old school in South Kensington to celebrate its 125th anniversary and officially open its new science laboratories.
Camilla took a trip down memory lane as she met current pupils, staff and other old girls at Queen's Gate School, where she studied during the late 50s and early 60s.
Her Royal Highness also took part in various experiments as she christened the new science facilities on Tuesday (February 23).
"I can't believe Queen's Gate has been going for 125 years, it feels like 125 years ago that I was here…," she said.
'It feels like 125 years ago that I was here'
"Queen's Gate must have given me a foundation and gave me a love of English and reading and for some unknown reason they have made me chancellor of Aberdeen University, so Queen's Gate must have taught me something."
The duchess was treated to fencing and wall-climbing demonstrations and a choir performance during her visit, and she took the opportunity to reminisce by flicking through some old school magazines.
She also met pupils taking part in BBC Radio 2's 500 Words competition, for which she is an honorary judge.
It was the first time she had returned to her old school, where sports and drama were among her favourite lessons, since opening its new junior school in 2007.
