The Royal Windsor Horse Show is one of the highlights of the Queen's calendar and takes place within the grounds of Windsor Castle.
Last year's equestrian event went virtual for the first time amid the COVID-19 and it was the first time the monarch missed the show since its launch in 1943.
The Queen looked delighted to be back at the show in July 2021 and was seen driving herself to the event after flying back to Windsor from her Scottish trip for the event's opening day.
Her Majesty, who learned how to ride at the age of three, has seen her own horses compete in the show.
She has often been pictured with her trusty camera around her neck and has been in the stands to support her husband, the late Duke of Edinburgh and her grandchildren, compete in carriage driving competitions.
Take a look back at these amazing photos of the Queen and her family at the Royal Windsor Horse Show over the years…
