Three horizontal bands of white, red and green, with a vertical red band on the hoist containing the national emblem — crossed swords with a khanjar dagger in white. White for peace; red has been Omani for centuries; green for the fertile Jebel Akhdar mountains. The national emblem is one of the world's oldest, dating from the 18th century.
