Monaco’s national flag consists of two equal horizontal bands—red over white—colors of the Grimaldi dynasty dating back to at least the 14th century. Its elegant simplicity reflects centuries of consistent principality symbolism.
Monaco Flag – Symbolism and Meaning
Monaco Flag - History and Origins
Adopted formally in 1881 under Prince Charles III, the two‑band design replaced earlier complex princely banners. Despite having the same palette as Indonesia, Monaco’s shorter 4:5 ratio and darker red distinguish it. A princely flag (white field with coat of arms) is used officially in government and royal settings.
Monaco Flag - Design Elements
Two horizontal bands of red (top) and white (bottom), each occupying half the height, in a 4:5 ratio. No additional emblem appears on the civil flag. The princely flag and personal standard feature heraldic devices or monograms on a white field.
Monaco Flag - Usage Guidelines and Protocol
The national flag is used by the public and at international venues like the United Nations. The princely flag flies at the palace and government buildings. Etiquette requires clean display, sunrise to sunset hoisting, and the flag not touching the ground. The red-white bicolor is never used on state flags without authorization.
