A network of a thousand beacons, traditional gun salutes and the illumination of the Houses of Parliament are among the ways the nation is celebrating the Queen's 90th.
Well-wishers are expected to sing Happy Birthday to the Queen when she goes on a walkabout close to her Windsor Castle home later to acknowledge the good wishes of the public.
And in the evening the night sky over her Berkshire home will be lit up by a beacon, started by the Queen, the first in a chain of more than 1,000 that will spread across the country and the globe.
Among the beacons being lit here in the Thames Valley; Wallingford, Thame, Thatcham, Newbury, Aldermaston, Bramley and Datchet.
The Houses of Parliament will also bit lit up red, white and blue in honour of the Queen's milestone.
