Huge crowds turned out to watch an action filled programme on 'Windsor Wednesday' of Royal Windsor Horse Show.
Joanna Peck, marketing director for Royal Windsor Horse Show, estimated they had between 8,000-10,000 people on the first day.
The Queen was spotted watching her horse, Tower Bridge, compete in the Novice Heavyweight Hunter show class and the Countess of Wessex also attended.
Other famous faces spotted in the crowd included former Olympians Jennie Loriston-Clarke and Jane Holderness-Roddam.
Dressage to music, where combinations perform a series of movements to a soundtrack of their choice, proved to be among the most popular events.
