When someone’s done the same job for 60 years, she deserves a party. And that’s what happened in London, England this week.

The party for Queen Elizabeth II lasted four days.

On the first day, she attended the Royal Derby, a big horserace held every year.

The second day, more than a million guests lined the River Thames and watched the Queen and members of her family float along in the royal barge, majestically surrounded by a flotilla of 1,000 boats. A flotilla is a group of small boats together on the water.
