Trivia: What country has the world’s oldest continuously used flag?
United Kingdom
Denmark
Japan
Iraq
The correct answer is Denmark
So why is this answer correct? : Since 1625, Denmark has flown a flag bearing a white cross against a red field. However, a similar rendition of the flag has existed since as far back as the 1370s. Many other countries have used similar designs, with the white cross as a symbol of Christianity. In Denmark, the flag is called the “Dannebrog” or “Danish cloth.”
