Her Majesty The Queen will visit Berkhamsted School to mark the 475th year since its foundation.
The official Buckingham Palace website says Queen Elizabeth II will arrive at the historical educational establishment on Friday, May 6 to celebrate the milestone.
The school’s anniversary celebrations will mark more than four centuries since it was founded in 1541 by John Incent, Dean of St Paul’s Cathedral.
Richard Backhouse, Principal of Berkhamsted School, said: “We are delighted to confirm that to mark the occasion of the 475th anniversary of the school, our patron, Her Majesty The Queen, has accepted an invitation to visit Berkhamsted School.
“This will be an exciting and historic occasion for the school as it is the first time, as far as records show, that a reigning monarch has visited.
“Preparations for the visit are underway and we look forward to welcoming Her Majesty in May.”
At this stage, the press office at Buckingham Palace were unable to provide any more information about the visit.
