The Queen is marking a major landmark today as she celebrates her 90th birthday.
Elizabeth II - who has been on the throne longer than any other monarch - will spend her actual birthday at Windsor Castle.
She will start by unveiling a 6.3km self-guided walking trail connecting 63 points of significance in the town.
In the evening, Her Majesty will light the first of a network of beacons throughout the country, including Kent, to mark the occasion.
Celebrations will continue from today until around the time of her official birthday, which this year is June 11.
