Trivia: How do Londoners know when the Queen is home at Buckingham?
Big Ben rings three times
A special flag is flown
The royal orchestra plays
The guards change uniforms
The correct answer is A special flag is flown
So why is this answer correct? : When Queen Elizabeth II is at home at Buckingham Palace, the Royal Standard flag is flown. The Royal Standard looks very different from the red, white, and blue pattern of the Union Jack flag. Instead, it features four quarters — the upper left and lower right corners feature three lions passant to represent England, the upper right corner shows a lion rampant to represent Scotland, and the harp in the lower left corner represents Ireland.
