Queen Elizabeth II celebrated her Sapphire Jubilee in 2016 and still isn't showing any signs of slowing down.
As the longest-reigning British monarch, she has ruled for a long and prosperous 65 years and has always been at the centre of the public eye.
Buckingham Palace marked momentous day, by re-releasing a beautiful portrait taken by British photographer David Bailey.
Over the past six decades the 90-year-old has seen it all - from the rise and fall of empires, new political leaders and of course, the changes in her very own family. But the Queen has always remained a constant, calming, omnipresent figure throughout history.
There is still so much about the British monarch that may surprise you!
