Happy Birthday to The Queen!

It is Queen Elizabeth II's 90th birthday on April 21, and she has certainly witnessed some incredible events in those nine decades.

To mark her big day, a train tour has gone through west London and the south east, while Kew gardens held a tree-planting in honour of Her Majesty and she will light a beacon later to trigger a chain reaction spanning the globe, including one in Hounslow .

In recent years, we have celebrated her diamond jubilee and watched countless speeches in front of the TV at Christmas.

In 10 more years she'll even qualify for a card from The Queen!

To celebrate, we have put together a quiz on some of the landmark events in our monarch's life and some other fiendish facts about her.
