Monaco
The flag of Monaco is the national flag of the Principality of Monaco. It has two equal horizontal bands, of red (top) and white (bottom), both of which have been the heraldic colours of the House of Grimaldi since at least 1339. The present bicolour design was adopted on 4 April 1881, under Charles III.
Monaco’s original flag, which was similar to its current princely flag but bore an older version of its coat of arms, was in use from the principality’s early days (except during its annexation to France from 1793 to 1814) until the present, simpler design was adopted in 1881.
The flag of Monaco is graphically identical to the flag of Indonesia, with differences in their dimension ratios (Monaco’s at 4:5 and Indonesia’s at 2:3), and the shade of red is darker for the flag of Monaco. The flag of Poland is also similar to that of Monaco, but with the colours reversed – white on top and red on the bottom.
