The Queen turned 80 years old on Friday and went to Windsor to meet hundreds of well wishers
Lots of children were among the excited onlookers waiting to give her gifts and shake her hand
Some were so keen to get a glimpse of the Queen that they even camped out all night!
Outside Windsor the King's Troop Royal Horse Artillery performed a 41 gun salute in Hyde Park
And the celebrations weren't only on land. Sailors on board the HMS Illustrious came up with their own way of wishing the Queen Happy Birthday
And as far away as New Zealand hundreds of people from all age groups formed a giant number 80 on the front lawn of Government House
