Today is Accession Day and marks 60 years since Liz succeeded the throne after her father, George VI, died in 1952.
The main celebrations will take place in June but today there will be lots of noise at noon... there will be a 41 gun salute in Hyde Park followed by a 62 gun salute at the Tower of London...

She's 85 you know. Eighty-five!
