Wimbledon is the biggest event in the British tennis calendar and it’s one of the oldest and most respected sporting events in the world. Every July, the best tennis players in the world come to Wimbledon to compete on the famous grass tennis courts. The tennis players have to wear all-white clothing during the competition, and it’s not unusual for royalty to be watching from the royal boxes on centre court. It’s a tradition for spectators to strawberries and cream during the competition.
