The Coat of Arms of Uruguay was first adopted by law on 19 March 1829. It consists of an oval, which is divided into four equal sections and crowned by a rising golden sun, the Sun of May, symbolizing the rising of the Uruguayan nation. The oval is surrounded by two olive branches, representing peace, joined at the bottom by a blue ribbon. In the upper left quarter, there is a scale, symbol of equality and justice, set on a blue background. The upper right quarter contains the Cerro de Montevideo (Montevideo Hill) with its fortress on the summit, which represents strength, on a silver background. In the lower left, also on a silver background, there is a galloping horse, symbolizing liberty. The lower right quarter holds an ox, which is a symbol of abundance, on a blue background.

The National Flag of Uruguay was officially adopted on 11 July 1830 and is described as follows: nine equal horizontal stripes of white (top and bottom) alternating with blue; a white square in the upper hoist-side corner with a yellow sun bearing a human face known as the Sun of May with 16 rays that alternate between triangular and wavy. dotThe Sun of May has been used as a national symbol since the 19th century. The nine blue and white stripes represent the nine departments within the country.
