If you look closely at the coat of arms in the center of the Dominican Republic's flag, you'll see an open Bible. It is the only country in the world to feature a Bible on its flag, symbolizing the faith of its people.

The blue on the flag represents liberty, the red signifies the blood of heroes who fought for independence, and the white cross means salvation and sacrifice. Each color is deeply imbued with the nation's history and identity from achieving independence from Haiti, making it especially meaningful.
