Buenos Aires, Argentina
The Argentinan flag was adopted on February 27, 1812 and contains 3 equally wide horizontal bands coloured light blue and white. In 1818 the yellow Sun of May was added to the flag. The Sun of May represents the Inca sun god Inti. The “of May” is in reference to the May Revolution in 1810 which marked the beginning of the independence from Spain. The Sun of May was originally an engraving on the first Argentine coin and was later used on only the battle flag. The sun on the official flag was not added until 1818.
